+File: latex2e.info, Node: Input encodings, Next: Ligatures, Up: Input text
+
+2.4.1 Input encodings
+---------------------
+
+The input to TeX (or any computer program) ultimately consists of a
+sequence of bytes. (Nowadays, a byte is almost universally an eight-bit
+number, i.e., an integer between 0 and 255, inclusive.) The input
+encoding defines how to interpret that sequence of bytes, and thus how
+LaTeX behaves.
+
+ Today, by far the most common way to encode text is with “UTF-8”, a
+so-called "Unicode Transformation Format" which specifies how to
+transform a sequence of 8-bit bytes to Unicode code points, which are
+defined independent of any particular representation. The Unicode
+encoding defines code points for virtually all characters used today in
+written text.
+
+ When TeX was created, Unicode and UTF-8 did not exist and the 7-bit
+ASCII encoding was by far the most widely used. So TeX does not require
+Unicode for text input. UTF-8 is a superset of ASCII, so a pure 7-bit
+ASCII document is also UTF-8.
+
+ Since 2018, the default input encoding for LaTeX is UTF-8. Some
+methods for handling documents written in some other encoding, such as
+ISO-8859-1 (Latin 1), are explained in *note inputenc package::.
+
+ You can easily find more about all these topics in any introductory
+computer text or online. For example, you might start at:
+<https://en.wikipedia.org/wiki/Unicode>.
+
+
+File: latex2e.info, Node: Ligatures, Next: Special characters, Prev: Input encodings, Up: Input text
+
+2.4.2 Ligatures
+---------------
+
+A “ligature” combines two or more letters (more generally, characters)
+into a single glyph. For example, in Latin-based typography, the two
+letters ‘f’ and ‘i’ are often combined into the glyph 'fi'.
+
+ TeX supports ligatures automatically. To continue the example, if
+the input has the word ‘fine’, written as four separate ASCII
+characters, TeX will output the word 'fine' (with the default fonts),
+with three typeset glyphs.
+
+ In traditional TeX, the available ligatures, if any, are defined by
+the current font. TeX also uses the ligature mechanism to produce a few
+typographical characters which were not available in any computer
+encoding when TeX was invented. In all, in the original Computer Modern
+fonts, the following input character sequences are defined to lead to
+ligatures:
+
+‘ff’
+ ff (ff ligature, U+FB00)
+‘fi’
+ fi (fi ligature, U+FB01)
+‘fl’
+ fl (fl ligature, U+FB02)
+‘ffi’
+ ffi (ffi ligature, U+FB03)
+‘ffl’
+ ffl (ffl ligature, U+FB04)
+‘``’
+ " (left double quotation mark, U+201C)
+‘''’
+ " (right double quotation mark, U+201D)
+‘--’
+ - (en-dash, U+2013)
+‘---’
+ -- (em-dash, U+2014)
+‘!`’
+ !' (inverted exclamation mark, U+00A1)
+‘?`’
+ ?' (inverted question mark, U+00BF)
+
+(For the f-ligatures above, the text in parentheses shows the individual
+characters, so in the typeset output you can easily see the difference
+between the ligature and the original character sequence.)
+
+ Nowadays it's usually possible to directly input the punctuation
+characters as Unicode characters, and LaTeX supports that (see previous
+section). But even today, it can still often be useful to use the ASCII
+ligature input form; for example, the difference between an en-dash and
+em-dash, as a single glyph, can be all but impossible to discern, but
+the difference between two and three ASCII hyphen characters is clear.
+Similarly with quotation marks, in some fonts.
+
+ Thus, even the engines with native support for UTF-8, namely LuaTeX
+and XeTeX, also support the ASCII ligature input sequences by default,
+independent of the font used. They also need to do so for
+compatibility.
+
+ By the way, the f-ligatures are also available in Unicode (the
+"Alphabetic Presentation Forms" block starting at U+FB00), but it's
+almost never desirable to use them as input characters, since in
+principle it should be up to the typesetter and the current font whether
+to use ligatures. Also, in practice, using them will typically cause
+searches to fail, that is, a search for the two characters ‘fi’ will not
+be matched by the ligature 'fi' at U+FB01.

+2.4.3 Special characters: ‘\ { } % $ & _ ^ # ~’

+“special characters”. Here they are:

+ Introduce a subscript or superscript, respectively, in math (*note
+ Subscripts & superscripts::); they produce an error outside math
+ mode. As a little-used special feature, two superscript characters
+ in a row can introduce special notation for an arbitrary character.

-3.3.2 Class and package commands
---------------------------------
-
-These are the commands designed to help writers of classes or packages.
-
-‘\AtBeginDvi{specials}’
- Save in a box register things that are written to the ‘.dvi’ file
- at the beginning of the shipout of the first page of the document.
-
-‘\AtEndOfClass{CODE}’
-‘\AtEndOfPackage{CODE}’
- Hook to insert CODE to be executed when LaTeX finishes processing
- the current class or package. You can use these hooks multiple
- times; the ‘code’ will be executed in the order that you called it.
- See also *note \AtBeginDocument::.
-
-‘\CheckCommand{CMD}[NUM][DEFAULT]{DEFINITION}’
-‘\CheckCommand*{CMD}[NUM][DEFAULT]{DEFINITION}’
- Like ‘\newcommand’ (*note \newcommand & \renewcommand::) but does
- not define CMD; instead it checks that the current definition of
- CMD is exactly as given by DEFINITION and is or is not “long” as
- expected. A long command is a command that accepts ‘\par’ within
- an argument. The CMD command is expected to be long with the
- unstarred version of ‘\CheckCommand’. Raises an error when the
- check fails. This allows you to check before you start redefining
- ‘cmd’ yourself that no other package has already redefined this
- command.
-
-‘\ClassError{CLASS NAME}{ERROR TEXT}{HELP TEXT}’
-‘\ClassWarning{CLASS NAME}{WARNING TEXT}’
-‘\ClassWarningNoLine{CLASS NAME}{WARNING TEXT}’
-‘\ClassInfo{CLASS NAME}{INFO TEXT}’
-‘\ClassInfoNoLine{CLASS NAME}{INFO TEXT}’
-‘\PackageError{PACKAGE NAME}{ERROR TEXT}{HELP TEXT}’
-‘\PackageWarning{PACKAGE NAME}{WARNING TEXT}’
-‘\PackageWarningNoLine{PACKAGE NAME}{WARNING TEXT}’
-‘\PackageInfo{PACKAGE NAME}{INFO TEXT}’
-‘\PackageInfoNoLine{PACKAGE NAME}{INFO TEXT}’
- Produce an error message, or warning or informational messages.
-
- For ‘\ClassError’ and ‘\PackageError’ the message is ERROR TEXT,
- followed by TeX’s ‘?’ error prompt. If the user then asks for help
- by typing ‘h’, they see the HELP TEXT.
-
- The four warning commands are similar except that they write
- WARNING TEXT on the screen with no error prompt. The four info
- commands write INFO TEXT only in the transcript file. The ‘NoLine’
- versions do not show the number of the line generating the message,
- while the other versions do show that number.
-
- To format the messages, including the HELP TEXT: use ‘\protect’ to
- stop a command from expanding, get a line break with
- ‘\MessageBreak’, and get a space with ‘\space’ when a space
- character does not allow it, like after a command. Note that LaTeX
- appends a period to the messages.
-
-‘\CurrentOption’
- Expands to the name of the currently-being-processed option. Can
- only be used within the CODE argument of either ‘\DeclareOption’ or
- ‘\DeclareOption*’.
-
-‘\DeclareOption{OPTION}{CODE}’
-‘\DeclareOption*{CODE}’
- Make an option available to a user to invoke in their
- ‘\documentclass’ command. For example, the ‘smcmemo’ class could
- have an option ‘\documentclass[logo]{smcmemo}’ allowing users to
- put the institutional logo on the first page. The class file must
- contain ‘\DeclareOption{logo}{CODE}’ (and later,
- ‘\ProcessOptions’).
-
- If you request an option that has not been declared, by default
- this will produce a warning like ‘Unused global option(s):
- [badoption].’ Change this behavior with the starred version
- ‘\DeclareOption*{CODE}’. For example, many classes extend an
- existing class, using a command such as ‘\LoadClass{article}’, and
- for passing extra options to the underlying class use code such as
- this.
-
- \DeclareOption*{%
- \PassOptionsToClass{\CurrentOption}{article}%
- }
-
- Another example is that the class ‘smcmemo’ may allow users to keep
- lists of memo recipients in external files. Then the user could
- invoke ‘\documentclass[math]{smcmemo}’ and it will read the file
- ‘math.memo’. This code handles the file if it exists and otherwise
- passes the option to the ‘article’ class.
-
- \DeclareOption*{\InputIfFileExists{\CurrentOption.memo}{}{%
- \PassOptionsToClass{\CurrentOption}{article}}}
-
-‘\DeclareRobustCommand{CMD}[NUM][DEFAULT]{DEFINITION}’
-‘* \DeclareRobustCommand*{CMD}[NUM][DEFAULT]{DEFINITION}’
- Like ‘\newcommand’ and ‘\newcommand*’ (*note \newcommand &
- \renewcommand::) but these declare a robust command, even if some
- code within the DEFINITION is fragile. (For a discussion of robust
- and fragile commands *note \protect::.) Use this command to define
- new robust commands or to redefine existing commands and make them
- robust. Unlike ‘\newcommand’ these do not give an error if macro
- CMD already exists; instead, a log message is put into the
- transcript file if a command is redefined.
-
- Commands defined this way are a bit less efficient than those
- defined using ‘\newcommand’ so unless the command’s data is fragile
- and the command is used within a moving argument, use
- ‘\newcommand’.
-
- The ‘etoolbox’ package offers the commands ‘\newrobustcmd’,
- ‘\newrobustcmd*’, as well as the commands ‘\renewrobustcmd’,
- ‘\renewrobustcmd*’, and the commands ‘\providerobustcmd’, and
- ‘\providerobustcmd*’. These are similar to ‘\newcommand’,
- ‘\newcommand*’, ‘\renewcommand’, ‘\renewcommand*’,
- ‘\providecommand’, and ‘\providecommand*’, but define a robust CMD
- with two advantages as compared to ‘\DeclareRobustCommand’:
- 1. They use the low-level e-TeX protection mechanism rather than
- the higher level LaTeX ‘\protect’ mechanism, so they do not
- incur the slight loss of performance mentioned above, and
- 2. They make the same distinction between ‘\new...’, ‘\renew...’,
- and ‘\provide...’, as the standard commands, so they do not
- just make a log message when you redefine CMD that already
- exists, in that case you need to use either ‘\renew...’ or
- ‘\provide...’ or you get an error.
-
-‘\IfFileExists{FILENAME}{TRUE CODE}{FALSE CODE}’
-‘\InputIfFileExists{FILENAME}{TRUE CODE}{FALSE CODE}’
- Execute TRUE CODE if LaTeX finds the file ‘FILE NAME’ or FALSE CODE
- otherwise. In the first case it executing TRUE CODE and then
- inputs the file. Thus the command
-
- \IfFileExists{img.pdf}{%
- \includegraphics{img.pdf}}{\typeout{!! img.pdf not found}
-
- will include the graphic ‘img.pdf’ if it is found and otherwise
- give a warning.
-
- This command looks for the file in all search paths that LaTeX
- uses, not only in the current directory. To look only in the
- current directory do something like ‘\IfFileExists{./filename}{TRUE
- CODE}{FALSE CODE}’. If you ask for a filename without a ‘.tex’
- extension then LaTeX will first look for the file by appending the
- ‘.tex’; for more on how LaTeX handles file extensions see *note
- \input::.
-
-‘\LoadClass[OPTIONS LIST]{CLASS NAME}[RELEASE DATE]’
-‘\LoadClassWithOptions{CLASS NAME}[RELEASE DATE]’
- Load a class, as with ‘\documentclass[OPTIONS LIST]{CLASS
- NAME}[RELEASE INFO]’. An example is
- ‘\LoadClass[twoside]{article}’.
-
- The OPTIONS LIST, if present, is a comma-separated list. The
- RELEASE DATE is optional. If present it must have the form
- YYYY/MM/DD.
-
- If you request a RELEASE DATE and the date of the package installed
- on your system is earlier, then you get a warning on the screen and
- in the log like this.
-
- You have requested, on input line 4, version `2038/01/19' of
- document class article, but only version `2014/09/29 v1.4h
- Standard LaTeX document class' is available.
-
- The command version ‘\LoadClassWithOptions’ uses the list of
- options for the current class. This means it ignores any options
- passed to it via ‘\PassOptionsToClass’. This is a convenience
- command that lets you build classes on existing ones, such as the
- standard ‘article’ class, without having to track which options
- were passed.
-
-‘\ExecuteOptions{OPTIONS-LIST}’
- For each option OPTION in the OPTIONS-LIST, in order, this command
- executes the command ‘\ds@OPTION’. If this command is not defined
- then that option is silently ignored.
-
- It can be used to provide a default option list before
- ‘\ProcessOptions’. For example, if in a class file you want the
- default to be 11pt fonts then you could specify
- ‘\ExecuteOptions{11pt}\ProcessOptions\relax’.
-
-‘\NeedsTeXFormat{FORMAT}[FORMAT DATE]’
- Specifies the format that this class must be run under. Often
- issued as the first line of a class file, and most often used as:
- ‘\NeedsTeXFormat{LaTeX2e}’. When a document using that class is
- processed, the format name given here must match the format that is
- actually being run (including that the FORMAT string is case
- sensitive). If it does not match then execution stops with an
- error like ‘This file needs format `LaTeX2e' but this is `xxx'.’
-
- To specify a version of the format that you know to have certain
- features, include the optional FORMAT DATE on which those features
- were implemented. If present it must be in the form ‘YYYY/MM/DD’.
- If the format version installed on your system is earlier than
- FORMAT DATE then you get a warning like this.
-
- You have requested release `2038/01/20' of LaTeX, but only
- release `2016/02/01' is available.
-
-‘\OptionNotUsed’
- Adds the current option to the list of unused options. Can only be
- used within the CODE argument of either ‘\DeclareOption’ or
- ‘\DeclareOption*’.
-
-‘\PassOptionsToClass{OPTION LIST}{CLASS NAME}’
-‘\PassOptionsToPackage{OPTION LIST}{PACKAGE NAME}’
- Adds the options in the comma-separated list OPTION LIST to the
- options used by any future ‘\RequirePackage’ or ‘\usepackage’
- command for package PACKAGE NAME or the class CLASS NAME.
-
- The reason for these commands is: you may load a package any number
- of times with no options but if you want options then you may only
- supply them when you first load the package. Loading a package
- with options more than once will get you an error like ‘Option
- clash for package foo.’ (LaTeX throws an error even if there is no
- conflict between the options.)
-
- If your own code is bringing in a package twice then you can
- collapse that to once, for example replacing the two
- ‘\RequirePackage[landscape]{geometry}’ and
- ‘\RequirePackage[margins=1in]{geometry}’ with the single command
- ‘\RequirePackage[landscape,margins=1in]{geometry}’.
-
- However, imagine that you are loading ‘firstpkg’ and inside that
- package it loads ‘secondpkg’, and you need the second package to be
- loaded with option ‘draft’. Then before doing the first package
- you must queue up the options for the second package, like this.
-
- \PassOptionsToPackage{draft}{secondpkg}
- \RequirePackage{firstpkg}
-
- (If ‘firstpkg.sty’ loads an option in conflict with what you want
- then you may have to alter its source.)
-
- These commands are useful for general users as well as class and
- package writers. For instance, suppose a user wants to load the
- ‘graphicx’ package with the option ‘draft’ and also wants to use a
- class ‘foo’ that loads the ‘graphicx’ package, but without that
- option. The user could start their LaTeX file with
- ‘\PassOptionsToPackage{draft}{graphicx}\documentclass{foo}’.
-
-‘\ProcessOptions’
-‘\ProcessOptions*\@OPTIONS’
- Execute the code for each option that the user has invoked.
- Include it in the class file as ‘\ProcessOptions\relax’ (because of
- the existence of the starred command).
-
- Options come in two types. “Local options” have been specified for
- this particular package in the OPTIONS argument of
- ‘\PassOptionsToPackage{OPTIONS}’, ‘\usepackage[OPTIONS]’, or
- ‘\RequirePackage[OPTIONS]’. “Global options” are those given by
- the class user in ‘\documentclass[OPTIONS]’ (If an option is
- specified both locally and globally then it is local.)
-
- When ‘\ProcessOptions’ is called for a package ‘pkg.sty’, the
- following happens:
- 1. For each option OPTION so far declared with ‘\DeclareOption’,
- it looks to see if that option is either a global or a local
- option for ‘pkg’. If so then it executes the declared code.
- This is done in the order in which these options were given in
- ‘pkg.sty’.
- 2. For each remaining local option, it executes the command
- ‘\ds@’OPTION if it has been defined somewhere (other than by a
- ‘\DeclareOption’); otherwise, it executes the default option
- code given in ‘\DeclareOption*’. If no default option code
- has been declared then it gives an error message. This is
- done in the order in which these options were specified.
-
- When ‘\ProcessOptions’ is called for a class it works in the same
- way except that all options are local, and the default CODE for
- ‘\DeclareOption*’ is ‘\OptionNotUsed’ rather than an error.
-
- The starred version ‘\ProcessOptions*’ executes the options in the
- order specified in the calling commands, rather than in the order
- of declaration in the class or package. For a package this means
- that the global options are processed first.
-
-‘\ProvidesClass{CLASS NAME}[RELEASE DATE BRIEF ADDITIONAL INFORMATION]’
-‘\ProvidesClass{CLASS NAME}[RELEASE DATE]’
-‘\ProvidesPackage{PACKAGE NAME}[RELEASE DATE BRIEF ADDITIONAL INFORMATION]’
-‘\ProvidesPackage{PACKAGE NAME}[RELEASE DATE]’
- Identifies the class or package, printing a message to the screen
- and the log file.
-
- When you load a class or package, for example with
- ‘\documentclass{smcmemo}’ or ‘\usepackage{test}’, LaTeX inputs a
- file. If the name of the file does not match the class or package
- name declared in it then you get a warning. Thus, if you invoke
- ‘\documentclass{smcmemo}’, and the file ‘smcmemo.cls’ has the
- statement ‘\ProvidesClass{xxx}’ then you get a warning like ‘You
- have requested document class `smcmemo', but the document class
- provides 'xxx'.’ This warning does not prevent LaTeX from
- processing the rest of the class file normally.
-
- If you include the optional argument then you must include a date,
- before any spaces, of the form ‘YYYY/MM/DD’. The rest of the
- optional argument is free-form, although it traditionally
- identifies the class, and is written to the screen during
- compilation and to the log file. Thus, if your file ‘smcmemo.cls’
- contains the line ‘\ProvidesClass{smcmemo}[2008/06/01 v1.0 SMC memo
- class]’ and your document’s first line is ‘\documentclass{smcmemo}’
- then you will see ‘Document Class: smcmemo 2008/06/01 v1.0 SMC memo
- class’.
-
- The date in the optional argument allows class and package users to
- ask to be warned if the version of the class or package is earlier
- than RELEASE DATE. For instance, a user could enter
- ‘\documentclass{smcmemo}[2018/10/12]’ or
- ‘\usepackage{foo}[[2017/07/07]]’ to require a class or package with
- certain features by specifying that it must be released no earlier
- than the given date. (Although, in practice package users only
- rarely include a date, and class users almost never do.)
-
-‘\ProvidesFile{FILENAME}[ADDITIONAL INFORMATION]’
- Declare a file other than the main class and package files, such as
- configuration files or font definition files. Put this command in
- that file and you get in the log a string like ‘File: test.config
- 2017/10/12 config file for test.cls’ for FILENAME equal to
- ‘test.config’ and ADDITIONAL INFORMATION equal to ‘2017/10/12
- config file for test.cls’.
-
-‘\RequirePackage[OPTION LIST]{PACKAGE NAME}[RELEASE DATE]’
-‘\RequirePackageWithOptions{PACKAGE NAME}[RELEASE DATE]’
- Load a package, like the command ‘\usepackage’ (*note Additional
- packages::). The LaTeX development team strongly recommends use of
- these commands over Plain TeX’s ‘\input’; see the Class Guide. An
- example is ‘\RequirePackage[landscape,margin=1in]{geometry}’.
-
- The OPTION LIST, if present, is a comma-separated list. The
- RELEASE DATE, if present, must have the form YYYY/MM/DD. If the
- release date of the package as installed on your system is earlier
- than RELEASE DATE then you get a warning like ‘You have requested,
- on input line 9, version `2017/07/03' of package jhtest, but only
- version `2000/01/01' is available’.
-
- The ‘\RequirePackageWithOptions’ version uses the list of options
- for the current class. This means it ignores any options passed to
- it via ‘\PassOptionsToClass’. This is a convenience command to
- allow easily building classes on existing ones without having to
- track which options were passed.
-
- The difference between ‘\usepackage’ and ‘\RequirePackage’ is
- small. The ‘\usepackage’ command is intended for the document file
- while ‘\RequirePackage’ is intended for package and class files.
- Thus, using ‘\usepackage’ before the ‘\documentclass’ command
- causes LaTeX to give error like ‘\usepackage before
- \documentclass’, but you can use ‘\RequirePackage’ there.

writes the SECTION NAME text to the ‘.aux’ auxiliary file, moving it
there for use elsewhere in the document such as in the table of

+was fragile and is now robust (‘$...$’ has always been robust).
- In this example the ‘\caption’ command gives a mysterious error about

-because the ‘\(..\)’ in the section title expands to illegal TeX in the

+
+Synopsis:
+
+ \DeclareOption{OPTION}{CODE}
+ \DeclareOption*{OPTION}{CODE}
+
+ Define an option a user can include in their ‘\documentclass’
+command. For example, a class ‘smcmemo’ could have an option ‘logo’
+allowing users to put the institutional logo on the first page. The
+document would start with ‘\documentclass[logo]{smcmemo}’. To enable
+this, the class file must contain ‘\DeclareOption{logo}{CODE}’ (and
+later, ‘\ProcessOptions’).
+
+ If you request an option that has not been declared, by default this
+will produce a warning like ‘Unused global option(s): [badoption].’ This
+can be changed by using ‘\DeclareOption*{CODE}’, which executes CODE for
+any unknown option.
+
+ For example, many classes extend an existing class, using code such
+as ‘\LoadClass{article}’ (*note \LoadClass::). In this case, it makes
+sense to pass any otherwise-unknown options to the underlying class,
+like this:
+
+ \DeclareOption*{%
+ \PassOptionsToClass{\CurrentOption}{article}%
+ }
+
+ As another example, our class ‘smcmemo’ might allow users to keep
+lists of memo recipients in external files, so the user could invoke
+‘\documentclass[math]{smcmemo}’ and it will read the file ‘math.memo’.
+This code inputs the file if it exists, while if it doesn't, the option
+is passed to the ‘article’ class:
+
+ \DeclareOption*{\InputIfFileExists{\CurrentOption.memo}
+ {}{%
+ \PassOptionsToClass{\CurrentOption}{article}}}

+12.14.7 ‘\DeclareRobustCommand’
+-------------------------------
+
+Synopsis:
+
+ \DeclareRobustCommand{CMD}[NUM][DEFAULT]{DEFINITION}
+ \DeclareRobustCommand* (same parameters
+
+ ‘\DeclareRobustCommand’ and its starred form are generally like
+‘\newcommand’ and ‘\newcommand*’ (*note \newcommand & \renewcommand::),
+with the addition that they define a so-called “robust” command, even if
+some code within the DEFINITION is fragile. (For a discussion of robust
+and fragile commands, *note \protect::.)
+
+ Also unlike ‘\newcommand’, these do not give an error if macro CMD
+already exists; instead, a log message is put into the transcript file
+if a command is redefined. Thus, ‘\DeclareRobustCommand’ can be used to
+define new robust commands or to redefine existing commands, making them
+robust.
+
+ The starred form, ‘\DeclareRobustCommand*’, disallows the arguments
+from containing multiple paragraphs, just like the starred form of
+‘\newcommand’ and ‘\renewcommand’. The meaning of the arguments is the
+same.
+
+ Commands defined this way are a bit less efficient than those defined
+using ‘\newcommand’ so unless the command's data is fragile and the
+command is used within a moving argument, use ‘\newcommand’.
+
+ Related to this, the ‘etoolbox’ package offers three commands and
+their starred forms: ‘\newrobustcmd’(‘*’) ‘\renewrobustcmd’(‘*’), and
+‘\providerobustcmd’(‘*’). They are similar to ‘\newcommand’,
+‘\renewcommand’, and ‘\providecommand’ and their own starred forms, but
+define a robust CMD. They have two possible advantages compared to
+‘\DeclareRobustCommand’:
+
+ 1. They use the low-level e-TeX protection mechanism rather than the
+ higher-level LaTeX ‘\protect’ mechanism, so they do not incur the
+ slight loss of performance mentioned above, and
+
+ 2. They make the same distinction between ‘\new...’, ‘\renew...’, and
+ ‘\provide...’, as the standard commands. That is, they do not just
+ write a log message when you redefine CMD that already exists; you
+ need to use either ‘\renew...’ or ‘\provide...’, or you get an
+ error. This may or may not be a benefit.

+12.14.8 ‘\ExecuteOptions’
+-------------------------
+
+Synopsis:
+
+ \ExecuteOptions{OPTION-LIST}
+
+ For each option OPTION in OPTION-LIST, in order, this command
+executes the command ‘\ds@OPTION’. If this command is not defined then
+that option is silently ignored.
+
+ This can be used to provide a default option list before
+‘\ProcessOptions’. For example, if in a class file you want the default
+to be 11pt fonts then you could specify
+‘\ExecuteOptions{11pt}\ProcessOptions\relax’.

+----------------------------------------------
+
+Synopses:
+
+ \IfFileExists{FILENAME}{TRUE-CODE}{FALSE-CODE}
+ \InputIfFileExists{FILENAME}{TRUE-CODE}{FALSE-CODE}
+
+ ‘\IfFileExists’ executes TRUE-CODE if LaTeX finds the file ‘FILENAME’
+or FALSE-CODE otherwise. In the first case it executing TRUE-CODE and
+then inputs the file. Thus the command
+
+ \IfFileExists{img.pdf}{%
+ \includegraphics{img.pdf}}
+ {\typeout{!! img.pdf not found}
+
+will include the graphic ‘img.pdf’ if it is found and otherwise give a
+warning.
+
+ This command looks for the file in all search paths that LaTeX uses,
+not only in the current directory. To look only in the current
+directory do something like
+‘\IfFileExists{./FILENAME}{TRUE-CODE}{FALSE-CODE}’. If you ask for a
+filename without a ‘.tex’ extension then LaTeX will first look for the
+file by appending the ‘.tex’; for more on how LaTeX handles file
+extensions see *note \input::.
+
+ ‘\InputIfFileExists’ is similar, but, as the name states,
+automatically ‘\input’s FILENAME if it exists. The TRUE-CODE is
+executed just before the ‘\input’; if the file doesn't exist, the
+FALSE-CODE is executed. An example:
+
+ \InputIfFileExists{mypkg.cfg}
+ {\PackageInfo{Loading mypkg.cfg for configuration information}}

+
+ Adds the options in the comma-separated list OPTIONS to the options
+used by any future ‘\RequirePackage’ or ‘\usepackage’ command for the
+class CLSNAME or the package PKGNAME, respectively.
+
+ The reason for these commands is that although you may load a package
+any number of times with no options, if you can specify options only the
+first time you load the package. Loading a package with options more
+than once will get you an error like ‘Option clash for package foo.’.
+LaTeX throws an error even if there is no conflict between the options.
+
+ If your own code is bringing in a package twice then you can combine
+the calls; for example, replacing the two
+
+ \RequirePackage[landscape]{geometry}
+ \RequirePackage[margins=1in]{geometry}
+
+with the single command
+
+ \RequirePackage[landscape,margins=1in]{geometry}
+
+ However, suppose you are loading ‘firstpkg’ and inside that package
+it loads ‘secondpkg’, and you need ‘secondpkg’ to be loaded with option
+‘draft’. Then before load the first package you must tell LaTeX about
+the desired options for the second package, like this:
+
+ \PassOptionsToPackage{draft}{secondpkg}
+ \RequirePackage{firstpkg}
+
+If ‘firstpkg.sty’ loads an option in conflict with what you want then
+you may have to alter its source, or yours.
+
+ These commands are useful for general users as well as class and
+package writers. For instance, suppose a user wants to load the
+‘graphicx’ package with the option ‘draft’ and also wants to use a class
+‘foo’ that loads the ‘graphicx’ package, but without that option. The
+user could start their LaTeX file with
+‘\PassOptionsToPackage{draft}{graphicx} \documentclass{foo}’.

+--------------------------
+
+Synopsis:
+
+ \ProcessOptions\@OPTIONS
+ \ProcessOptions*\@OPTIONS
+
+ Execute the code for each option that the user has invoked. Invoke
+it in the class file as ‘\ProcessOptions\relax’ (because of the
+existence of the starred version, described below).
+
+ Options come in two types. “Local options” have been specified for
+this particular package in ‘\usepackage[OPTIONS]’,
+‘\RequirePackage[OPTIONS]’, or the OPTIONS argument of
+‘\PassOptionsToPackage{OPTIONS}’. “Global options” are those given by
+the class user in ‘\documentclass[OPTIONS]’. If an option is specified
+both locally and globally then it is local.
+
+ When ‘\ProcessOptions’ is called for a package ‘pkg.sty’, the
+following happens:
+
+ 1. For each option OPTION so far declared with ‘\DeclareOption’,
+ ‘\ProcessOptions’ looks to see if that option is either global or
+ local for ‘pkg’. If so, then it executes the declared code. This
+ is done in the order in which these options were given in
+ ‘pkg.sty’.
+
+ 2. For each remaining local option, it executes the command
+ ‘\ds@’OPTION if it has been defined somewhere (other than by a
+ ‘\DeclareOption’); otherwise, it executes the default option code
+ given in ‘\DeclareOption*’. If no default option code has been
+ declared then it gives an error message. This is done in the order
+ in which these options were specified.
+
+ When ‘\ProcessOptions’ is called for a class it works in the same way
+except that all options are local, and the default CODE for
+‘\DeclareOption*’ is ‘\OptionNotUsed’ rather than an error.
+
+ The starred version ‘\ProcessOptions*’ executes the options in the
+order specified in the calling commands, rather than in the order of
+declaration in the class or package. For a package, this means that the
+global options are processed first.

+ \ProvidesPackage{PKGNAME}[RELEASE-DATE [INFO-TEXT]]
+
+ Identifies the class or package being defined, printing a message to
+the screen and the log file.
+
+ When you load a class or package, for example with
+‘\documentclass{smcmemo}’ or ‘\usepackage{test}’, LaTeX inputs a file
+(‘smcmemo.cls’ and ‘test.sty’, respectively). If the name of the file
+does not match the class or package name declared in it then you get a
+warning. Thus, if you invoke ‘\documentclass{smcmemo}’, and the file
+‘smcmemo.cls’ has the statement ‘\ProvidesClass{foo}’ then you get a
+warning like ‘You have requested document class `smcmemo', but the
+document class provides 'foo'.’ This warning does not prevent LaTeX from
+processing the rest of the class file normally.
+
+ If you include the optional argument then you must include a date,
+before any spaces, of the form ‘YYYY/MM/DD’. The rest of the optional
+argument is free-form, although it traditionally identifies the class.
+It is written to the screen during compilation and to the log file.
+Thus, if your file ‘smcmemo.cls’ contains the line
+‘\ProvidesClass{smcmemo}[2008/06/01 v1.0 SMC memo class]’ and your
+document's first line is ‘\documentclass{smcmemo}’ then you will see
+‘Document Class: smcmemo 2008/06/01 v1.0 SMC memo class’.
+
+ The date in the optional argument allows class and package users to
+ask to be warned if the version of the class or package is earlier than
+RELEASE DATE. For instance, a user could enter
+‘\documentclass{smcmemo}[2018/10/12]’ or
+‘\usepackage{foo}[[2017/07/07]]’ to require a class or package with
+certain features by specifying that it must be released no earlier than
+the given date. Perhaps more importantly, the date serves as
+documentation of the last release. (In practice, package users rarely
+include a date, and class users almost never do.)

+ Load a package, like the command ‘\usepackage’ (*note Additional
+packages::). An example:
+‘\RequirePackage[landscape,margin=1in]{geometry}’
+
+ The initial optional argument OPTION-LIST, if present, must be a
+comma-separated list. The trailing optional argument RELEASE-DATE, if
+present, must have the form ‘YYYY/MM/DD’. If the release date of the
+package as installed on your system is earlier than RELEASE-DATE then
+you get a warning like ‘You have requested, on input line 9, version
+`2017/07/03' of package jhtest, but only version `2000/01/01' is
+available’.
+
+ The ‘\RequirePackageWithOptions’ variant uses the list of options for
+the current class. This means it ignores any options passed to it via
+‘\PassOptionsToClass’. This is a convenience command to allow easily
+building classes on existing ones without having to track which options
+were passed.
+
+ The difference between ‘\usepackage’ and ‘\RequirePackage’ is small.
+The ‘\usepackage’ command is intended to be used in documents, while
+‘\RequirePackage’ is intended for package and class files. The most
+significant difference in practice is that ‘\RequirePackage’ can be used
+in a document before the ‘\documentclass’ command, while ‘\usepackage’
+gives an error there. The most common need for this nowadays is for the
+‘\DocumentMetadata’ command (*note \DocumentMetadata::).
+
+ The LaTeX development team strongly recommends use of these and
+related commands over Plain TeX's ‘\input’; see the Class Guide
+(<https://ctan.org/pkg/clsguide>).

-
- \usepackage[COMMA-SEPARATED OPTION LIST]{color}
-
- When you load the ‘color’ package there are two kinds of available
-options.
-
- The first specifies the “printer driver”. LaTeX doesn’t contain
-information about different output systems but instead depends on
-information stored in a file. Normally you should not specify the
-driver option in the document, and instead rely on your system’s
-default. One advantage of this is that it makes the document portable

-currently relevant ones are: ‘dvipdfmx’, ‘dvips’, ‘dvisvgm’, ‘luatex’,
-‘pdftex’, ‘xetex’. The two ‘xdvi’ and ‘oztex’ are essentially aliases
-for ‘dvips’ (and ‘xdvi’ is monochrome). Ones that should not be used

-21.2 Color models
-=================
-
-A “color model” is a way of representing colors. LaTeX’s capabilities
-depend on the printer driver. However, the ‘pdftex’, ‘xetex’, and
-‘luatex’ printer drivers are today by far the most commonly used. The
-models below work for those drivers. All but one of these is also
-supported by essentially all other printer drivers used today.
-
- Note that color combination can be additive or subtractive. Additive
-mixes colors of light, so that for instance combining full intensities
-of red, green, and blue produces white. Subtractive mixes pigments,
-such as with inks, so that combining full intensity of cyan, magenta,
-and yellow makes black.
-
-‘cmyk’
- A comma-separated list with four real numbers between 0 and 1,
- inclusive. The first number is the intensity of cyan, the second
- is magenta, and the others are yellow and black. A number value of
- 0 means minimal intensity, while a 1 is for full intensity. This
- model is often used in color printing. It is a subtractive model.
-
-‘gray’
- A single real number between 0 and 1, inclusive. The colors are
- shades of grey. The number 0 produces black while 1 gives white.
-
-‘rgb’
- A comma-separated list with three real numbers between 0 and 1,
- inclusive. The first number is the intensity of the red component,
- the second is green, and the third the blue. A number value of 0
- means that none of that component is added in, while a 1 means full
- intensity. This is an additive model.
-
-‘RGB’
- (‘pdftex’, ‘xetex’, ‘luatex’ drivers) A comma-separated list with
- three integers between 0 and 255, inclusive. This model is a
- convenience for using ‘rgb’ since outside of LaTeX colors are often
- described in a red-green-blue model using numbers in this range.
- The values entered here are converted to the ‘rgb’ model by
- dividing by 255.
-
-‘named’
- Colors are accessed by name, such as ‘PrussianBlue’. The list of
- names depends on the driver, but all support the names ‘black’,
- ‘blue’, ‘cyan’, ‘green’, ‘magenta’, ‘red’, ‘white’, and ‘yellow’
- (See the ‘dvipsnames’ option in *note Color package options::).

---------------------
-
-Synopsis:
-
- \definecolor{NAME}{MODEL}{SPECIFICATION}
-
- Give the name NAME to the color. For example, after this
-
- \definecolor{silver}{rgb}{0.75,0.75,0.74}
-
-you can use that color name with ‘Hi ho, \textcolor{silver}{Silver}!’.
-
- This example gives the color a more abstract name, so it could change
-and not be misleading.
-
- \definecolor{logocolor}{RGB}{145,92,131} % RGB needs pdflatex
- \newcommand{\logo}{\textcolor{logocolor}{Bob's Big Bagels}}
-
- Often a document’s colors are defined in the preamble, or in the
-class or style, rather than in the document body.

-
-Synopses:
-
- \textcolor{NAME}{...}
- \textcolor[COLOR MODEL]{COLOR SPECIFICATION}{...}
-
-or
-
- \color{NAME}
- \color[COLOR MODEL]{COLOR SPECIFICATION}
-
- The affected text gets the color. This line
-
- \textcolor{magenta}{My name is Ozymandias, King of Kings;}
- Look on my works, ye Mighty, and despair!
-
-causes the first half to be in magenta while the rest is in black. You
-can use a color declared with ‘\definecolor’ in exactly the same way
-that we just used the builtin color ‘magenta’.
-
- \definecolor{MidlifeCrisisRed}{rgb}{1.0,0.11,0.0}
- I'm thinking about getting a \textcolor{MidlifeCrisisRed}{sports car}.
-
- The two ‘\textcolor’ and ‘\color’ differ in that the first is a
-command form, enclosing the text to be colored as an argument. Often
-this form is more convenient, or at least more explicit. The second
-form is a declaration, as in ‘The moon is made of {\color{green} green}
-cheese’, so it is in effect until the end of the current group or
-environment. This is sometimes useful when writing macros or as below
-where it colors everything inside the ‘center’ environment, including
-the vertical and horizontal lines.
-
- \begin{center} \color{blue}
- \begin{tabular}{l|r}
- UL &UR \\ \hline
- LL &LR
- \end{tabular}
- \end{center}
-
- You can use color in equations. A document might have this
-definition in the preamble
-
- \definecolor{highlightcolor}{RGB}{225,15,0}
-
-and then contain this equation.
-
- \begin{equation}
- \int_a^b \textcolor{highlightcolor}{f'(x)}\,dx=f(b)-f(a)
- \end{equation}
-
- Typically the colors used in a document are declared in a class or
-style but sometimes you want a one-off. Those are the second forms in
-the synopses.
-
- Colors of \textcolor[rgb]{0.33,0.14,0.47}{Purple} and
- {\color[rgb]{0.72,0.60,0.37}Gold} for the team.
-
- The format of COLOR SPECIFICATION depends on the color model (*note
-Color models::). For instance, while ‘rgb’ takes three numbers, ‘gray’
-takes only one.
-
- The selection was \textcolor[gray]{0.5}{grayed out}.
-
- Colors inside colors do not combine. Thus
-
- \textcolor{green}{kind of \textcolor{blue}{blue}}
-
-has a final word that is blue, not a combination of blue and green.

- \colorbox[MODEL NAME]{BOX BACKGROUND COLOR}{...}
-

- \fcolorbox{FRAME COLOR}{BOX BACKGROUND COLOR}{...}
- \fcolorbox[MODEL NAME]{FRAME COLOR}{BOX BACKGROUND COLOR}{...}
-
- Make a box with the stated background color. The ‘\fcolorbox’
-command puts a frame around the box. For instance this
-
- Name:~\colorbox{cyan}{\makebox[5cm][l]{\strut}}
-
-makes a cyan-colored box that is five centimeters long and gets its
-depth and height from the ‘\strut’ (so the depth is ‘-.3\baselineskip’
-and the height is ‘\baselineskip’). This puts white text on a blue
-background.
-
- \colorbox{blue}{\textcolor{white}{Welcome to the machine.}}
-
- The ‘\fcolorbox’ commands use the same parameters as ‘\fbox’ (*note
-\fbox & \framebox::), ‘\fboxrule’ and ‘\fboxsep’, to set the thickness
-of the rule and the boundary between the box interior and the
-surrounding rule. LaTeX’s defaults are ‘0.4pt’ and ‘3pt’, respectively.
-
- This example changes the thickness of the border to 0.8 points. Note

+
+ The two ‘\textcolor’ and ‘\color’ differ in that the first is a

+this form is more convenient, or at least more explicit. The second
+form is a declaration, as in ‘The moon is made of {\color{green} green}
+cheese’, so it is in effect until the end of the current group or
+environment. This is sometimes useful when writing macros or as below
+where it colors everything inside the ‘center’ environment, including
