+LPPL Version 1.3c  2008-05-04
+
+Copyright 1999 2002-2008 LaTeX3 Project
+    Everyone is allowed to distribute verbatim copies of this
+    license document, but modification of it is not allowed.
+
+
+PREAMBLE
+========
+
+The LaTeX Project Public License (LPPL) is the primary license under
+which the LaTeX kernel and the base LaTeX packages are distributed.
+
+You may use this license for any work of which you hold the copyright
+and which you wish to distribute.  This license may be particularly
+suitable if your work is TeX-related (such as a LaTeX package), but 
+it is written in such a way that you can use it even if your work is 
+unrelated to TeX.
+
+The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE',
+below, gives instructions, examples, and recommendations for authors
+who are considering distributing their works under this license.
+
+This license gives conditions under which a work may be distributed
+and modified, as well as conditions under which modified versions of
+that work may be distributed.
+
+We, the LaTeX3 Project, believe that the conditions below give you
+the freedom to make and distribute modified versions of your work
+that conform with whatever technical specifications you wish while
+maintaining the availability, integrity, and reliability of
+that work.  If you do not see how to achieve your goal while
+meeting these conditions, then read the document `cfgguide.tex'
+and `modguide.tex' in the base LaTeX distribution for suggestions.
+
+
+DEFINITIONS
+===========
+
+In this license document the following terms are used:
+
+   `Work'
+    Any work being distributed under this License.
+    
+   `Derived Work'
+    Any work that under any applicable law is derived from the Work.
+
+   `Modification' 
+    Any procedure that produces a Derived Work under any applicable
+    law -- for example, the production of a file containing an
+    original file associated with the Work or a significant portion of
+    such a file, either verbatim or with modifications and/or
+    translated into another language.
+
+   `Modify'
+    To apply any procedure that produces a Derived Work under any
+    applicable law.
+    
+   `Distribution'
+    Making copies of the Work available from one person to another, in
+    whole or in part.  Distribution includes (but is not limited to)
+    making any electronic components of the Work accessible by
+    file transfer protocols such as FTP or HTTP or by shared file
+    systems such as Sun's Network File System (NFS).
+
+   `Compiled Work'
+    A version of the Work that has been processed into a form where it
+    is directly usable on a computer system.  This processing may
+    include using installation facilities provided by the Work,
+    transformations of the Work, copying of components of the Work, or
+    other activities.  Note that modification of any installation
+    facilities provided by the Work constitutes modification of the Work.
+
+   `Current Maintainer'
+    A person or persons nominated as such within the Work.  If there is
+    no such explicit nomination then it is the `Copyright Holder' under
+    any applicable law.
+
+   `Base Interpreter' 
+    A program or process that is normally needed for running or
+    interpreting a part or the whole of the Work.    
+
+    A Base Interpreter may depend on external components but these
+    are not considered part of the Base Interpreter provided that each
+    external component clearly identifies itself whenever it is used
+    interactively.  Unless explicitly specified when applying the
+    license to the Work, the only applicable Base Interpreter is a
+    `LaTeX-Format' or in the case of files belonging to the 
+    `LaTeX-format' a program implementing the `TeX language'.
+
+
+
+CONDITIONS ON DISTRIBUTION AND MODIFICATION
+===========================================
+
+1.  Activities other than distribution and/or modification of the Work
+are not covered by this license; they are outside its scope.  In
+particular, the act of running the Work is not restricted and no
+requirements are made concerning any offers of support for the Work.
+
+2.  You may distribute a complete, unmodified copy of the Work as you
+received it.  Distribution of only part of the Work is considered
+modification of the Work, and no right to distribute such a Derived
+Work may be assumed under the terms of this clause.
+
+3.  You may distribute a Compiled Work that has been generated from a
+complete, unmodified copy of the Work as distributed under Clause 2
+above, as long as that Compiled Work is distributed in such a way that
+the recipients may install the Compiled Work on their system exactly
+as it would have been installed if they generated a Compiled Work
+directly from the Work.
+
+4.  If you are the Current Maintainer of the Work, you may, without
+restriction, modify the Work, thus creating a Derived Work.  You may
+also distribute the Derived Work without restriction, including
+Compiled Works generated from the Derived Work.  Derived Works
+distributed in this manner by the Current Maintainer are considered to
+be updated versions of the Work.
+
+5.  If you are not the Current Maintainer of the Work, you may modify
+your copy of the Work, thus creating a Derived Work based on the Work,
+and compile this Derived Work, thus creating a Compiled Work based on
+the Derived Work.
+
+6.  If you are not the Current Maintainer of the Work, you may
+distribute a Derived Work provided the following conditions are met
+for every component of the Work unless that component clearly states
+in the copyright notice that it is exempt from that condition.  Only
+the Current Maintainer is allowed to add such statements of exemption 
+to a component of the Work. 
+
+  a. If a component of this Derived Work can be a direct replacement
+     for a component of the Work when that component is used with the
+     Base Interpreter, then, wherever this component of the Work
+     identifies itself to the user when used interactively with that
+     Base Interpreter, the replacement component of this Derived Work
+     clearly and unambiguously identifies itself as a modified version
+     of this component to the user when used interactively with that
+     Base Interpreter.
+     
+  b. Every component of the Derived Work contains prominent notices
+     detailing the nature of the changes to that component, or a
+     prominent reference to another file that is distributed as part
+     of the Derived Work and that contains a complete and accurate log
+     of the changes.
+  
+  c. No information in the Derived Work implies that any persons,
+     including (but not limited to) the authors of the original version
+     of the Work, provide any support, including (but not limited to)
+     the reporting and handling of errors, to recipients of the
+     Derived Work unless those persons have stated explicitly that
+     they do provide such support for the Derived Work.
+
+  d. You distribute at least one of the following with the Derived Work:
+
+       1. A complete, unmodified copy of the Work; 
+          if your distribution of a modified component is made by
+          offering access to copy the modified component from a
+          designated place, then offering equivalent access to copy
+          the Work from the same or some similar place meets this
+          condition, even though third parties are not compelled to
+          copy the Work along with the modified component;
+
+       2. Information that is sufficient to obtain a complete,
+          unmodified copy of the Work.
+
+7.  If you are not the Current Maintainer of the Work, you may
+distribute a Compiled Work generated from a Derived Work, as long as
+the Derived Work is distributed to all recipients of the Compiled
+Work, and as long as the conditions of Clause 6, above, are met with
+regard to the Derived Work.
+
+8.  The conditions above are not intended to prohibit, and hence do not
+apply to, the modification, by any method, of any component so that it
+becomes identical to an updated version of that component of the Work as
+it is distributed by the Current Maintainer under Clause 4, above.
+
+9.  Distribution of the Work or any Derived Work in an alternative
+format, where the Work or that Derived Work (in whole or in part) is
+then produced by applying some process to that format, does not relax or
+nullify any sections of this license as they pertain to the results of
+applying that process.
+     
+10. a. A Derived Work may be distributed under a different license
+       provided that license itself honors the conditions listed in
+       Clause 6 above, in regard to the Work, though it does not have
+       to honor the rest of the conditions in this license.
+      
+    b. If a Derived Work is distributed under a different license, that
+       Derived Work must provide sufficient documentation as part of
+       itself to allow each recipient of that Derived Work to honor the 
+       restrictions in Clause 6 above, concerning changes from the Work.
+
+11. This license places no restrictions on works that are unrelated to
+the Work, nor does this license place any restrictions on aggregating
+such works with the Work by any means.
+
+12.  Nothing in this license is intended to, or may be used to, prevent
+complete compliance by all parties with all applicable laws.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for the Work.  Except when otherwise stated in
+writing, the Copyright Holder provides the Work `as is', without
+warranty of any kind, either expressed or implied, including, but not
+limited to, the implied warranties of merchantability and fitness for a
+particular purpose.  The entire risk as to the quality and performance
+of the Work is with you.  Should the Work prove defective, you assume
+the cost of all necessary servicing, repair, or correction.
+
+In no event unless required by applicable law or agreed to in writing
+will The Copyright Holder, or any author named in the components of the
+Work, or any other party who may distribute and/or modify the Work as
+permitted above, be liable to you for damages, including any general,
+special, incidental or consequential damages arising out of any use of
+the Work or out of inability to use the Work (including, but not limited
+to, loss of data, data being rendered inaccurate, or losses sustained by
+anyone as a result of any failure of the Work to operate with any other
+programs), even if the Copyright Holder or said author or said other
+party has been advised of the possibility of such damages.
+
+
+MAINTENANCE OF THE WORK
+=======================
+
+The Work has the status `author-maintained' if the Copyright Holder
+explicitly and prominently states near the primary copyright notice in
+the Work that the Work can only be maintained by the Copyright Holder
+or simply that it is `author-maintained'.
+
+The Work has the status `maintained' if there is a Current Maintainer
+who has indicated in the Work that they are willing to receive error
+reports for the Work (for example, by supplying a valid e-mail
+address). It is not required for the Current Maintainer to acknowledge
+or act upon these error reports.
+
+The Work changes from status `maintained' to `unmaintained' if there
+is no Current Maintainer, or the person stated to be Current
+Maintainer of the work cannot be reached through the indicated means
+of communication for a period of six months, and there are no other
+significant signs of active maintenance.
+
+You can become the Current Maintainer of the Work by agreement with
+any existing Current Maintainer to take over this role.
+
+If the Work is unmaintained, you can become the Current Maintainer of
+the Work through the following steps:
+
+ 1.  Make a reasonable attempt to trace the Current Maintainer (and
+     the Copyright Holder, if the two differ) through the means of
+     an Internet or similar search.
+
+ 2.  If this search is successful, then enquire whether the Work
+     is still maintained.
+
+  a. If it is being maintained, then ask the Current Maintainer
+     to update their communication data within one month.
+     
+  b. If the search is unsuccessful or no action to resume active
+     maintenance is taken by the Current Maintainer, then announce
+     within the pertinent community your intention to take over
+     maintenance.  (If the Work is a LaTeX work, this could be
+     done, for example, by posting to comp.text.tex.)
+
+ 3a. If the Current Maintainer is reachable and agrees to pass
+     maintenance of the Work to you, then this takes effect
+     immediately upon announcement.
+     
+  b. If the Current Maintainer is not reachable and the Copyright
+     Holder agrees that maintenance of the Work be passed to you,
+     then this takes effect immediately upon announcement.  
+    
+ 4.  If you make an `intention announcement' as described in 2b. above
+     and after three months your intention is challenged neither by
+     the Current Maintainer nor by the Copyright Holder nor by other
+     people, then you may arrange for the Work to be changed so as
+     to name you as the (new) Current Maintainer.
+     
+ 5.  If the previously unreachable Current Maintainer becomes
+     reachable once more within three months of a change completed
+     under the terms of 3b) or 4), then that Current Maintainer must
+     become or remain the Current Maintainer upon request provided
+     they then update their communication data within one month.
+
+A change in the Current Maintainer does not, of itself, alter the fact
+that the Work is distributed under the LPPL license.
+
+If you become the Current Maintainer of the Work, you should
+immediately provide, within the Work, a prominent and unambiguous
+statement of your status as Current Maintainer.  You should also
+announce your new status to the same pertinent community as
+in 2b) above.
+
+
+WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
+======================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+works under this license.  These authors are addressed as `you' in
+this section.
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your work you want or need to use *distribution*
+conditions that differ significantly from those in this license, then
+do not refer to this license anywhere in your work but, instead,
+distribute your work under a different license.  You may use the text
+of this license as a model for your own license, but your license
+should not refer to the LPPL or otherwise give the impression that
+your work is distributed under the LPPL.
+
+The document `modguide.tex' in the base LaTeX distribution explains
+the motivation behind the conditions of this license.  It explains,
+for example, why distributing LaTeX under the GNU General Public
+License (GPL) was considered inappropriate.  Even if your work is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their works under any
+license are encouraged to read it.
+
+A Recommendation on Modification Without Distribution
+-----------------------------------------------------
+
+It is wise never to modify a component of the Work, even for your own
+personal use, without also meeting the above conditions for
+distributing the modified component.  While you might intend that such
+modifications will never be distributed, often this will happen by
+accident -- you may forget that you have modified that component; or
+it may not occur to you when allowing others to access the modified
+version that you are thus distributing it and violating the conditions
+of this license in ways that could have legal implications and, worse,
+cause problems for the community.  It is therefore usually in your
+best interest to keep your copy of the Work identical with the public
+one.  Many works provide ways to control the behavior of that work
+without altering any of its licensed components.
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the components of your work both
+an explicit copyright notice including your name and the year the work
+was authored and/or last substantially modified.  Include also a
+statement that the distribution and/or modification of that
+component is constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+  %% pig.dtx
+  %% Copyright 2008 M. Y. Name
+  %
+  % This work may be distributed and/or modified under the
+  % conditions of the LaTeX Project Public License, either version 1.3
+  % of this license or (at your option) any later version.
+  % The latest version of this license is in
+  %   https://www.latex-project.org/lppl.txt
+  % and version 1.3c or later is part of all distributions of LaTeX
+  % version 2008 or later.
+  %
+  % This work has the LPPL maintenance status `maintained'.
+  % 
+  % The Current Maintainer of this work is M. Y. Name.
+  %
+  % This work consists of the files pig.dtx and pig.ins
+  % and the derived file pig.sty.
+
+Given such a notice and statement in a file, the conditions
+given in this license document would apply, with the `Work' referring
+to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
+generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
+referring to any `LaTeX-Format', and both `Copyright Holder' and
+`Current Maintainer' referring to the person `M. Y. Name'.
+
+If you do not want the Maintenance section of LPPL to apply to your
+Work, change `maintained' above into `author-maintained'.  
+However, we recommend that you use `maintained', as the Maintenance
+section was added in order to ensure that your Work remains useful to
+the community even when you can no longer maintain and support it
+yourself.
+
+Derived Works That Are Not Replacements
+---------------------------------------
+
+Several clauses of the LPPL specify means to provide reliability and
+stability for the user community. They therefore concern themselves
+with the case that a Derived Work is intended to be used as a
+(compatible or incompatible) replacement of the original Work. If
+this is not the case (e.g., if a few lines of code are reused for a
+completely different task), then clauses 6b and 6d shall not apply.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes the Work
+
+   The LPPL requires that distributions of the Work contain all the
+   files of the Work.  It is therefore important that you provide a
+   way for the licensee to determine which files constitute the Work.
+   This could, for example, be achieved by explicitly listing all the
+   files of the Work near the copyright notice of each file or by
+   using a line such as:
+
+    % This work consists of all files listed in manifest.txt.
+   
+   in that place.  In the absence of an unequivocal list it might be
+   impossible for the licensee to determine what is considered by you
+   to comprise the Work and, in such a case, the licensee would be
+   entitled to make reasonable conjectures as to which files comprise
+   the Work.

+# didactic
+
+This package provides macros and environments useful for writing teaching 
+material. It provides more semantic environments on top of the standard 
+`definition`, `theorem`, and friends: for instance, `exercise`, `activity` and 
+`question`. These are suitably colour coded when used with Beamer. They occur 
+as "normal" text in handouts produced by `beamerarticle` (same style as 
+`definition` usually has).
+
+It also provides macros for typesetting code listings and output side by side.
+
+Finally, it modifies the appearance of `beamer` (Berlin based theme) and 
+`memoir` (Tufte style layout), if loaded. It's designed to be used with 
+`beamer` to produce slides and `beamerarticle` with `memoir` to produce notes, 
+and handouts from the same source.
+
+## Installation
+
+To use the package, you only need to install `didactic.sty` in a place where 
+your LaTeX distribution can find it. For a local installation, you can put it
+in the same directory as your document, or in `~/texmf/tex/latex/didactic/`.
+
+Actually, for the latter, you can simply do the following:
+
+```bash
+mkdir -p ~/texmf/tex/latex
+cd ~/texmf/tex/latex
+git clone https://github.com/dbosk/didactic.git
+cd didactic
+make all
+```
+
+That will build both `didactic.sty` and `didactic.pdf`. The documentation is 
+located in `didactic.pdf`.
+

+maintainer.

+% \section{Introduction}
+%
+% This package introduces some environments that are useful for writing 
+% teaching material.
+% It also provides a few settings for |beamer| and |memoir| to make the 
+% resulting document more readable.
+%
+% \section{Usage}
+%
+% The package automatically detects if |beamer| or |memoir| is loaded and 
+% customizes the document accordingly.
+% \DescribeEnv{nobeamer}
+% \DescribeEnv{noarticle}
+% \DescribeEnv{nomemoir}
+% That can be prevented, however, by using the |nobeamer| or |nomemoir| 
+% options.
+% The |noarticle| is to prevent the article versions of the (|beamer|) 
+% environments to be defined.
+%
+% \DescribeEnv{notheorems}
+% The package also provides a few environments for |beamer| and |article| mode.
+% Particularly, it can define theorems and definitions, which might be defined 
+% also by other packages.
+% To prevent this, use the |notheorems| option.
+%
+% \DescribeEnv{inner}
+% \DescribeEnv{outer}
+% \DescribeEnv{top}
+% \DescribeEnv{bottom}
+% When the package customizes |memoir| it sets the inner and outer margins to 
+% fit margin notes better.
+% The |inner| and |outer| options can be used to set the inner and outer 
+% margins to be used.
+% The |top| and |bottom| options can be used to set the top and bottom margins.
+%
+% \subsection{Beamer blocks and semantic environments for papers}
+%
+% \DescribeEnv{assumption}
+% \DescribeEnv{idea}
+% \DescribeEnv{question}
+% \DescribeEnv{exercise}
+% \DescribeEnv{activity}
+% \DescribeEnv{remark}
+% These environments provides wrappers around Beamer's |block| environment.
+% The idea is to complement the blocks provided by Beamer, such as |theorem|, 
+% |definition| and |example|, with some more useful blocks.
+% Each of them provides a block with an appropriate title and optional subtitle 
+% and is of a suitable colour.
+% For instance, consider the following.
+% \input{idea.tex}
+% That can be produced by the following code.
+% \inputminted[linenos]{latex}{idea.tex}
+%
+% \DescribeMacro{\ProvideSemanticEnv}
+% We can create new such block environments, that work both with |beamer| and
+% without, by using the |\ProvideSemanticEnv| command.
+% This command takes five arguments:
+% \begin{enumerate}
+% \item the name of the environment,
+% \item the name of the block environment to use (optional),
+% \item the title of the block,
+% \item options to pass to |thmtools| (optional),
+% \item the key of the translation of the refname of the block,
+% \item the key of the translation of the refnames of the block.
+% \item the key of the translation of the Refname of the block,
+% \item the key of the translation of the Refnames of the block.
+% \end{enumerate}
+% For example, the |idea| block above was created by the following code:
+% \inputminted{latex}{ProvideSemanticEnv.tex}
+%
+% \DescribeEnv{lightblock}
+% \DescribeEnv{darkblock}
+% We provide two shades of boxes, light coloured and dark coloured boxes.
+% These can be used to create boxes of various colours easily.
+% These two environments take two mandatory arguments: the first one is a 
+% colour, the second is the title.
+%
+% In the text (not slides) the blocks are not coloured.
+% For instance, consider the following.
+% \input{lightblock.tex}
+% That can be produced by the following code.
+% \inputminted[linenos]{latex}{lightblock.tex}
+%
+% \DescribeEnv{blackblock}
+% \DescribeEnv{whiteblock}
+% \DescribeEnv{bwblock}
+% For instance, we provide a black block, white block and a black-white block.
+% These take only one mandatory argument: a title.
+%
+% \DescribeEnv{redblock}
+% \DescribeEnv{blueblock}
+% \DescribeEnv{purpleblock}
+% \DescribeEnv{greenblock}
+% \DescribeEnv{yellowblock}
+% \DescribeEnv{orangeblock}
+% We also provide a few predefined blocks in various common colours.
+% They all take a title as mandatory argument.
+%
+% \subsection{Tools for code examples}
+%
+% We also provide two commands for working with code examples: |lstexample| and 
+% |runpython|.
+%
+% \DescribeMacro{\lstexample}
+% The |\lstexample| command allows us to typeset the source code of the 
+% example.
+% For instance, |\lstexample{python}{hello.py}| produces the following:
+% \lstexample{python}{hello.py}
+%
+% We can also pass optional arguments directly to |minted| that is used to 
+% typeset the code.
+% \begin{example}
+% |\lstexample[linenos,highlightlines=4]{python}{hello.py}| produces the 
+% following.
+% \lstexample[linenos,highlightlines=4]{python}{hello.py}
+% \end{example}
+%
+% \DescribeMacro{\runpython}
+% We can also run the example code and include its output using the 
+% |\runpython| macro.
+% \begin{example}
+% For instance, |\runpython{hello.py}| produces the following.
+% \runpython{hello.py}
+% \end{example}
+%
+% \DescribeMacro{\codebycode}
+% The |\codebycode| command is simply two |\lstexample| commands side by side:
+% |\codebycode[opt1]{lang1}{file1}[opt2]{lang2}{file2}|.
+% \codebycode
+%   [breaklines,linenos]{python}{hello.py}
+%   [breaklines,linenos,highlightlines=4]{python}{hello.py}
+%
+% \DescribeMacro{\runbyrun}
+% We can also put the output side by side using 
+% |\runbyrun{hello.py}{hello.py}|.
+% \runbyrun{hello.py}{hello.py}
+%
+% \subsection{Adding margin notes of different kinds}
+%
+% \DescribeMacro{\indentedmarginpar}
+% We want to be able to put quite some content in the margins.
+% For this reason we want to have indented paragraphs in the margin notes.
+% We can use the |\indentedmarginpar{text}| command to do this.
+% For instance, consider the output in the margin.
+% \indentedmarginpar{%
+%   This is an example of an indented margin paragraph.
+%
+%   It can contain multiple paragraphs.
+% }
+%
+% \DescribeMacro{\newnotetype}
+% \DescribeMacro{\ltnote}
+% We also want to be able to use titled notes of different kinds.
+% We can use the |\newnotetype[fmtcmd]{type}{title}| command to define a new 
+% type of note.
+% For instance |\ltnote| is defined as
+% \begin{center}
+% |\newnotetype{\ltnote}{\GetTranslationWarn{Learning theory}}|.
+% \end{center}
+% \ltnote{This is an example of a learning theory note.}
+%
+% We can also change the formatting of the title.
+% |\newnotetype[\textbf]{\bfnote}{Bold note}| and
+% |\bfnote{This is a bold note.}| gives us the note in the margin.
+% \newnotetype[\textbf]{\bfnote}{Bold note}
+% \bfnote{This is a bold note.}
+% \ltnote{Another example of a learning theory note.}
+%
+% \StopEventually{}
+%
+% \section{Implementation}
+%
+% Let's start with the options.
+%
+% \subsection{Options}
+%
+% We have a few negative options, that is, if specified we don't want to do 
+% them.
+% This means that we'll need to use conditionals.
+% So each option definition consists first of a |\newif| then setting it to 
+% true, and finnally, a |\DeclareOption|.
+% The body of the |\DeclareOption| then sets the |\if| to false.
+% After all the options are declared we'll use |\ProcessOptions|.
+% After that we can have all code actually doing the work, all wrapped in |\if| 
+% statements.
+%
+% \begin{environment}{nobeamer}
+% \begin{environment}{nobeamertheme}
+% \begin{environment}{noarticle}
+% This option is used to disable the |beamer| specific parts of the package.
+% Meaning that we don't customize |beamer| even when we find that it is loaded.
+%    \begin{macrocode}
+\newif\if@didactic@beamer
+\@ifclassloaded{beamer}{\@didactic@beamertrue}{\@didactic@beamerfalse}
+\DeclareOptionX{nobeamer}{\@didactic@beamerfalse}
+\newif\if@didactic@article
+\@ifclassloaded{beamer}{\@didactic@articlefalse}{\@didactic@articletrue}
+\newif\if@didactic@beamertheme
+\@didactic@beamerthemetrue
+\DeclareOptionX{nobeamertheme}{\@didactic@beamerthemefalse}
+\DeclareOptionX{noarticle}{\@didactic@articlefalse}
+%    \end{macrocode}
+% \end{environment}
+% \end{environment}
+% \end{environment}
+%
+% \begin{environment}{nomemoir}
+% This option is used to disable the |memoir| specific parts of the package.
+% Meaning that we don't customize |memoir| even when we find that it is loaded.
+%    \begin{macrocode}
+\newif\if@didactic@memoir
+\@ifclassloaded{memoir}{\@didactic@memoirtrue}{\@didactic@memoirfalse}
+\DeclareOptionX{nomemoir}{\@didactic@memoirfalse}
+%    \end{macrocode}
+% \end{environment}
+%
+% \begin{environment}{notheorems}
+% This option is used to disable defining the usual environments provided by 
+% |amsmath|: definition, theorem, etc.
+%    \begin{macrocode}
+\newif\if@didactic@theorems
+\@didactic@theoremstrue
+\DeclareOptionX{notheorems}{\@didactic@theoremsfalse}
+%    \end{macrocode}
+% \end{environment}
+%
+% \begin{environment}{inner}
+% \begin{environment}{outer}
+% \begin{environment}{top}
+% \begin{environment}{bottom}
+% We also have some key--value options to control the margins.
+%    \begin{macrocode}
+\newcommand\@didactic@margin@inner{20mm}
+\newcommand\@didactic@margin@outer{70mm}
+\newcommand\@didactic@margin@top{25mm}
+\newcommand\@didactic@margin@bottom{40mm}
+\DeclareOptionX{inner}[25mm]{\renewcommand\@didactic@margin@inner{#1}}
+\DeclareOptionX{outer}[65mm]{\renewcommand\@didactic@margin@outer{#1}}
+\DeclareOptionX{top}[25mm]{\renewcommand\@didactic@margin@top{#1}}
+\DeclareOptionX{bottom}[40mm]{\renewcommand\@didactic@margin@bottom{#1}}
+%    \end{macrocode}
+% \end{environment}
+% \end{environment}
+% \end{environment}
+% \end{environment}
+%
+% \begin{environment}{marginparmargin}
+% We also have an option to set the marginpar margin.
+% We simply pass this on to |memoir| and keep a record ourselves too.
+% We know that the default in |memoir| is |outer|.
+%    \begin{macrocode}
+\newcommand\@didactic@marginparmargin{outer}
+\DeclareOptionX{marginparmargin}{%
+  \renewcommand\@didactic@marginparmargin{#1}
+  \@ifclassloaded{memoir}{%
+    \marginparmargin{#1}
+    \strictpagechecktrue
+    \checkandfixthelayout
+  }{}
+}
+%    \end{macrocode}
+% \end{environment}
+%
+% Now that we've declared the options we can process them.
+%    \begin{macrocode}
+\ProcessOptionsX\relax
+%    \end{macrocode}
+%
+% \subsection{Customizing \texttt{beamer}}
+%
+% If |beamer| is loaded we want to customize it.
+% However, only if the user hasn't disabled this with the |nobeamer| option.
+%    \begin{macrocode}
+\if@didactic@beamer
+%    \end{macrocode}
+
+% If we use |beamer| we want to use the Berlin theme.
+% This theme guides the viewer very nicely, how must is left and where we are
+% in the presentation.
+% (The same is true for the presenter.)
+%    \begin{macrocode}
+\if@didactic@beamertheme
+  \usetheme{Berlin}
+%    \end{macrocode}
+% However, we want to customize the footline.
+% We want to add two lines in the footline.
+% We want to add the author (left) and institute (right) to the first line.
+% Then we add the title (left) and page number (right) to the bottom line.
+%    \begin{macrocode}
+  \setbeamertemplate{footline}%{miniframes theme}
+  {%
+    \begin{beamercolorbox}[colsep=1.5pt]{upper separation line foot}
+    \end{beamercolorbox}
+    \begin{beamercolorbox}[ht=2.5ex,dp=1.125ex,%
+      leftskip=.3cm,rightskip=.3cm plus1fil]{author in head/foot}%
+      \leavevmode{\usebeamerfont{author in head/foot}\insertshortauthor}%
+      \hfill%
+      {\usebeamerfont{institute in head/foot}%
+        \usebeamercolor[fg]{institute in head/foot}\insertshortinstitute}%
+    \end{beamercolorbox}%
+    \begin{beamercolorbox}[ht=2.5ex,dp=1.125ex,%
+      leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}%
+      {\usebeamerfont{title in head/foot}\insertshorttitle}%
+      \hfill%
+      \insertframenumber%
+    \end{beamercolorbox}%
+    \begin{beamercolorbox}[colsep=1.5pt]{lower separation line foot}
+    \end{beamercolorbox}
+  }
+%    \end{macrocode}
+%
+% We also want to set the transparency of the covered items.
+% We also want to set the bibliography item to text, we need this to get proper 
+% references (not icons) in the bibliography.
+% (We need that for certain bibliography styles.)
+%    \begin{macrocode}
+  \setbeamercovered{transparent}
+  \setbeamertemplate{bibliography item}{\relax}
+\fi
+%    \end{macrocode}
+%
+% Finally, we want to add a table of contents at the beginning of each section 
+% and subsection.
+% We want these to be shaded, so that the current section is highlighted.
+% We also want to hide the subsections of the other sections.
+%    \begin{macrocode}
+\AtBeginSection[]{%
+  \begin{frame}<beamer>
+    \tableofcontents[currentsection,
+                     subsectionstyle=show/show/hide]
+  \end{frame}
+}
+\AtBeginSubsection[]{%
+  \begin{frame}<beamer>
+    \tableofcontents[currentsection,
+                     subsectionstyle=show/shaded/hide]
+  \end{frame}
+}
+\fi% end \if@didactic@beamer
+%    \end{macrocode}
+%
+% \subsection{Customizing \texttt{memoir}}
+%
+% If |memoir| is loaded we want to customize it.
+% However, only if the user hasn't disabled this with the |nomemoir| option.
+%    \begin{macrocode}
+\if@didactic@memoir
+%    \end{macrocode}
+%
+% We want to set up |memoir| to use the Tufte style.
+% This means that we want to put a lot of text in the margin.
+% We'll use margin notes and put all the footnotes in the margin.
+% We also want to use footnotes for references so that they also appear in the
+% margin.
+%
+% We want to use the |marginfix| package to fix the margin notes.
+%    \begin{macrocode}
+\RequirePackage{marginfix}

+%
+% We also want to adapt the citation commands of a few packages to use 
+% footnotes.
+% For these, we check if the package is loaded, if it is, we do the changes.
+% We don't load the packages ourselves, we assume the user has done that.
+% This also means that the |didactic| package should be loaded last.

+%
+% And that concludes the |memoir| part.
+%    \begin{macrocode}
+\fi% end \if@didactic@memoir
+%    \end{macrocode}
+%
+% \subsection{A side-caption environment for \texttt{beamer}}
+%
+% \begin{environment}{sidecaption}
+% When using |memoir|, we can use the |sidecaption| environment to put the 
+% caption in the margin.
+% However, when using |beamer| we don't have this environment, so we need to 
+% provide it with a suitable behaviour.
+% It's suitable to just translate it to a normal caption, as usually used in 
+% |beamer|.
+%    \begin{macrocode}
+\ProvideDocumentEnvironment{sidecaption}{omo+b}{%
+  #4
+  \caption{#2\IfValueT{#3}{\label{#3}}}
+}{\relax}
+%    \end{macrocode}
+% \end{environment}
+%
+% \begin{macro}{\flushscap}
+% We also want to provide a command to flush a figure towards the caption.
+%    \begin{macrocode}
+\NewDocumentCommand{\flushscap}{O{\centering}}{%
+  \@ifclassloaded{memoir}{%
+    \ifscapmargleft%
+      \flushleft%
+    \else%
+      \flushright%
+    \fi%
+  }{%
+    #1%
+  }%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+% \subsection{More semantic environments}
+%
+% We want to provide a set of environments (blocks) for |beamer|.
+% We want the names of the blocks to be translated.
+% We'll use the |translations| package for this.
+% That way we get the language used through the normal use of |babel|.
+%
+% We also want to have the same environments for the article mode, but in a 
+% nicer format that the default of |beamerarticle|.
+% For instance, instead of
+% \begin{block}{Example}
+% This is an example.
+% \end{block}
+% we want something like
+% \begin{example}
+% This is an example.
+% \end{example}
+%
+% This means that we'll need to do one thing if |beamer| is loaded and another 
+% if |beamerarticle| is loaded---or rather, when |beamer| is not loaded, we 
+% should be able to use this without |beamer| and |beamerarticle|.
+%
+% We want to provide environments like this one:
+% \begin{exercise}\label{exercise}
+%   This is an exercise.
+% \end{exercise}
+% \begin{exercise}\label{anotherexercise}
+%   This is another exercise.
+% \end{exercise}
+% We can use |\cref| to refer to them, getting something like \cref{exercise} or 
+% \cref{exercise,anotherexercise}.
+%
+% We also want it to work with different languages, provided there is a
+% translation.
+% We do Swedish here.
+%
+% \selectlanguage{swedish}
+% Vi kan också skapa exempel på svenska.
+% \begin{exercise}\label{exempel}
+%   Detta är ett exempel.
+% \end{exercise}
+% \begin{exercise}\label{ytterligareexempel}
+%   Detta är ytterligare ett exempel.
+% \end{exercise}
+% Vi kan referera till dem med |\cref|, vilket ger något som \cref{exempel}
+% eller \cref{exempel,ytterligareexempel}.
+% \selectlanguage{british}
+%
+% Let's also add another idea, but in Swedish.
+%
+% \selectlanguage{swedish}
+% \begin{idea}\label{ide}
+%   Detta är en idé.
+% \end{idea}
+% Då har vi \cref{ide}, men vi hade även tidigare \cref{theidea}.
+% Tillsammans är de \cref{ide,theidea}.
+% \selectlanguage{british}
+%
+% We can also refer to them in English, \cref{ide} and \cref{theidea}
+% separately and together as \cref{ide,theidea}.
+%
+% \begin{macro}{\ProvideSemanticEnv}
+% We provide a command to create such environments.
+% This way we just run this command in the preamble, if |beamer| is loaded it 
+% creates the block environments for |beamer|, otherwise it creates the 
+% environments for the article.
+%
+% It can be used like this:
+% \begin{center}
+% |\ProvideSemanticEnv{test}[alertblock]{Test}[style=definition]|\\
+% \qquad|{test}{tests}{Test}{Tests}|
+% \end{center}
+%    \begin{macrocode}
+\ProvideDocumentCommand{\ProvideSemanticEnv}{m o m o mmmm}{%
+  \@ifundefined{#1}{%
+    \@ifclassloaded{beamer}{% beamer
+%    \end{macrocode}
+% For |beamer| we want to use the |block| environment, or one of the coloured
+% blocks that we provide below.
+% We let the second argument (optional) be the name of the block environment to
+% use.
+% This will be the easiest way to set the colour of the block.
+%
+% Lastly, we let the third argument be the title of the block.
+% This is the English title and also the key used to translate the title of the
+% block.
+%    \begin{macrocode}
+      \IfValueTF{#2}{%
+        \ProvideDocumentEnvironment{#1}{o}{%
+          \begin{#2}{\GetTranslationWarn{#3}\IfValueT{##1}{: ##1}}
+        }{%
+          \end{#2}

+% \subsection{Adding margin notes of different kinds}
+%
+% We want to add titled margin notes.
+% These margin notes should use indentation since they might contains several 
+% paragraphs.
+%
+% \begin{macro}{\indentedmarginpar}
+% We start with the indented margin notes.
+% They simply take a text as argument and typeset it in the margin: 
+% |\indentedmarginpar{this is the text}|.
+% \indentedmarginpar{this is the text}
+%    \begin{macrocode}
+% Gives us indentation in the margin notes.
+% Adapted from https://tex.stackexchange.com/a/257171
+\NewDocumentCommand{\indentedmarginpar}{+m}{%
+  \@ifclassloaded{memoir}{\strictpagecheck}{\relax}%
+  \marginpar{%
+    \setlength{\parindent}{1.0em}\footnotesize
+    \@afterindentfalse\@afterheading #1
+  }%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\newnotetype}
+% Now, let's add a command to add margin notes with a title.
+% The |\newnotetype{\titlenote}{Title]| command creates a new command 
+% |\titlenote| that takes a text as argument and typesets it in the margin with 
+% the title |Title|: |\titlenote{this is the text}|.
+% \newnotetype{\titlenote}{Title}
+% \titlenote{this is the text}
+%    \begin{macrocode}
+\NewDocumentCommand{\newnotetype}{omm}{%
+  \IfValueTF{#1}
+    {\NewDocumentCommand{#2}{+m}{%
+      \indentedmarginpar{#1{#3:} ##1}%
+    }}
+    {\NewDocumentCommand{#2}{+m}{%
+      \indentedmarginpar{\emph{#3:} ##1}%
+    }}%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ltnote}
+% We provide a few different types of margin notes.
+% That way we can also include translations for them.
+%    \begin{macrocode}
+\ProvideTranslation{swedish}{Learning theory}{Lärandeteori}
+\newnotetype{\ltnote}{\GetTranslationWarn{Learning theory}}
+%    \end{macrocode}
+% \end{macro}
+%
+%
+%
+% \subsection{Listing and running code examples}
+%
+% Let's turn our focus to |\lstexample| and |\runpython|.
+% We want to make it easy to typeset and print the output of example Python 
+% programs in slides and texts.
+% We want to use PythonTeX to automatically run the code and typeset the source 
+% code using |minted|.
+%
+% These are the same for both |beamer| and article mode.
+%
+% \begin{macro}{\lstexample}
+% The first part is easy.
+% To typeset the source file we simply need to use the minted package.
+% We provide an optional argument to pass options to minted.
+%    \begin{macrocode}
+\NewDocumentCommand{\lstexample}{omm}{%
+  \IfValueTF{#1}
+    {\inputminted[escapeinside=||,#1]{#2}{#3}}
+    {\inputminted[escapeinside=||]{#2}{#3}}
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\runpython}
+% Now, for the second part, printing the output, we do this in two steps.
+% First, we create a function using PythonTeX that runs a Python program and 
+% prints it output.
+% We can use it like |\runpython{hello.py}| to run the program in |hello.py|.
+% The output is printed in verbatim mode.
+% Alternatively we could use |\runpython[opt]{hello.py}| to pass |opt| to the 
+% underlying |fancyvrb| environment.
+%
+% Let's create that function in PythonTeX to run the example program file.
+% We simply execute it with Python 3 and capture its output.
+% Then we print the output to stdout, which is then captured by PythonTeX.
+% We use |pytex.add_dependencies| to add the file as a dependency to rerun the 
+% code when necessary.
+%    \begin{macrocode}
+\begin{pycode}
+import subprocess
+
+def run_module(m):
+  result = subprocess.run(["python3", m], capture_output=True)
+  print(result.stdout.decode("utf8").strip())
+  pytex.add_dependencies(m)
+
+def mintedoutput(m, opt):
+  if opt:
+      print(r'\begin{minted}[{}]{{text}}'.format(opt))
+  else:
+      print(r'\begin{minted}{text}')
+  run_module(m)
+  print(r'\end{minted}')
+\end{pycode}
+%    \end{macrocode}
+%
+% Then we simply create a command that run that function with the file as 
+% argument.
+% Then print the output in verbatim mode.
+%    \begin{macrocode}
+\NewDocumentCommand{\runpython}{om}{%
+  \setpythontexautoprint{false}%
+  \pyc{run_module("#2")}%
+  \printpythontex[verbatim]%
+}
+%    \end{macrocode}
+% \end{macro}
+% 
+% \subsection{Contrasting code examples}
+%
+% Sometimes we want to contrast two code examples side by side.
+% \begin{macro}{\textbytext}
+% For example |\textbytext{\lipsum[1]}{\lipsum[1]}| should typeset the two 
+% examples side by side.
+% \textbytext{\lipsum[1]}{\lipsum[1]}
+% If we use the |memoir| class and our settings (|\if@didactic@memoir|), we 
+% want to use the |adjustwidth| environment to expand the text block to better 
+% fit them.
+% Otherwise we use the standard text block.
+%
+% To do this we first add a |fullwidth| environment\footnote{%
+%   Similarly to \url{https://tex.stackexchange.com/a/350944/17418}.
+% }.
+% We can get the |adjustwidth| environment from the |changepage| package 
+% whenever |memoir| isn't used.
+%    \begin{macrocode}
+\RequirePackage{changepage}
+\newlength{\@didactic@textbytext@oldcolumnwidth}
+\NewDocumentEnvironment{fullwidth}{+b}{%
+  \setlength{\@didactic@textbytext@oldcolumnwidth}{\columnwidth}
+  \setlength{\columnwidth}{\textwidth+2em+\marginparwidth+\marginparsep}
+  \IfStrEqCase{\@didactic@marginparmargin}{%
+    {inner}{\begin{adjustwidth*}{-\marginparwidth-\marginparsep}{-2em}}
+    {left}{\begin{adjustwidth}{-\marginparwidth-\marginparsep}{-2em}}
+    {outer}{\begin{adjustwidth*}{-2em}{-\marginparwidth-\marginparsep}}
+    {right}{\begin{adjustwidth}{-2em}{-\marginparwidth-\marginparsep}}
+  }[\relax]
+    #1
+  \IfStrEqCase{\@didactic@marginparmargin}{%
+    {inner}{\end{adjustwidth*}}
+    {left}{\end{adjustwidth}}
+    {outer}{\end{adjustwidth*}}
+    {right}{\end{adjustwidth}}
+  }[\relax]
+  \setlength{\columnwidth}{\@didactic@textbytext@oldcolumnwidth}
+}{\relax}
+%    \end{macrocode}
+%
+% Now to the |\textbytext| command.
+% We simply set up a |tabularx| environment with two columns and use it inside 
+% a |fullwidth| environment.
+%    \begin{macrocode}
+\NewDocumentCommand{\textbytext}{+m+m}{%
+  \begin{fullwidth}
+    \begin{tabularx}{\columnwidth}{XX}
+      #1 & #2
+    \end{tabularx}
+  \end{fullwidth}
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\codebycode}
+% When we deal with code, we deal with verbatim data.
+% The easiest way to deal with this is to simply keep the code in files and 
+% supply the file names to |\inputminted|.
+% The |\codebycode| command is simply two |\inputminted| commands side by side:
+% |\codebycode[opt1]{lang1}{file1}[opt2]{lang2}{file2}|.
+% \codebycode
+%   [breaklines,linenos]{python}{hello.py}
+%   [breaklines,linenos]{python}{hello.py}
+%
+% This gives us the following implementation.
+% We can reuse |\textbytext| to typeset the two examples side by side.
+%    \begin{macrocode}
+\RequirePackage{tabularx}
+\RequirePackage{minted}
+\NewDocumentCommand{\codebycode}{ommomm}{%
+  \textbytext{%
+    \IfValueTF{#1}
+      {\lstexample[#1]{#2}{#3}}
+      {\lstexample{#2}{#3}}%
+  }{%
+    \IfValueTF{#4}
+      {\lstexample[#4]{#5}{#6}}
+      {\lstexample{#5}{#6}}%
+  }%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\runbyrun}
+% We also want to typeset the runs (|\runpython|).
+% We can use |\textbytext| to typeset the two outputs side by side.
+%    \begin{macrocode}
+\NewDocumentCommand{\runbyrun}{mm}{%
+  \textbytext{\runpython{#1}}{\runpython{#2}}%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \Finale
