-Copyright (C) 2011-2012  Martin Scharrer <martin@scharrer-online.de>
-This program comes with ABSOLUTELY NO WARRANTY;

-
-Usage:
-  texdef   [options] commandname [commandname ...]
-  latexdef [options] commandname [commandname ...]
-
-Other program names are possible. See the 'tex' option.  Command names do not need to start with `\`.
-
-Options:
-  --tex <format>, -t <format>   : Use given format of TeX: 'tex', 'latex', 'context'.
-                                  Variations of 'tex' and 'latex', like 'luatex', 'lualatex', 'xetex', 'xelatex' are supported.
-                                  The default is given by the used program name: 'texdef' -> 'tex', 'latexdef' -> 'latex', etc.
-  --source, -s                  : Try to show the original source code of the command definition (L).
-  --value, -v                   : Show value of command instead (i.e. \the\command).
-  --Environment, -E             : Every command name is taken as an environment name. This will show the definition of
-                                  both \Macro\foo and \Macro\endfoo if \texttt{foo} is used as command name (L).
-  --preamble, -P                : Show definition of the command inside the preamble.
-  --beforeclass, -B             : Show definition of the command before \documentclass.
-  --package <pkg>, -p <pkg>     : (M) Load given tex-file, package or module depending on whether '*tex', '*latex'
-                                  or 'context' is used. For LaTeX the <pkg> can start with `[<options>]` and end 
-                                  with `<pkgname>` or `{<pkgname>}`.
-  --class <class>, -c <class>   : (LaTeX only) Load given class instead of default ('article').
-                                  The <class> can start with `[<classs options>]` and end 
-                                  with `<classname>` or `{<classname>}`.
-  --environment <env>, -e <env> : (M) Show definition inside the given environment <env>.
-  --othercode <code>, -o <code> : (M) Add other code into the preamble before the definition is shown.
-                                  This can be used to e.g. load PGF/TikZ libraries.
-  --before <code>, -b <code>    : (M) Place <code> before definition is shown.
-                                  The <code> can be arbitray TeX code and doesn't need be be balanced.
-  --after  <code>, -a <code>    : (M) Place <code> after definition is shown.
-                                  The <code> can be arbitray TeX code and doesn't need be be balanced.
-  --find, -f                    : Find file where the command sequence was defined (L).
-  --Find, -F                    : Show full filepath of the file where the command sequence was defined (L).
-  --list, -l                    : List user level command sequences of the given packages (L).
-  --list-defs, -L               : List user level command sequences and their shorten definitions of the given packages (L).
-  --list-all, -ll               : List all command sequences of the given packages (L).
-  --list-defs-all, -LL          : List all command sequences and their shorten definitions of the given packages (L).
-  --ignore-cmds <cs,cs,..>,  -i : Ignore the following command sequence(s) in the above lists. (M)
-  --ignore-regex <regex,..>, -I : Ignore all command sequences in the above lists which match the given Perl regular expression(s). (M)
-  --pgf-keys, -k                : Takes commands as pgfkeys and displays their definitions. Keys must use the full path but the common '.\@cmd' prefix is applied.
-  --pgf-Keys, -K                : Takes commands as pgfkeys and displays their definitions. Keys must use the full path.
-  --version, -V                 : If used alone prints version of this script.
-                                  (L) Together with -p or -c prints version of LaTeX package(s) or class, respectively.
-  --edit                        : Opens the file holding the macro definition. Uses --Find and --source. (L)
-                                  If the source definition can not be found the definition is printed as normal instead.
-  --editor <editor>             : Can be used to set the used editor. If not used the environment variables TEXDEF_EDITOR, EDITOR and
-                                  SELECTED_EDITOR are read in this order. If none of these are set a list of default
-                                  editors are tried.  The <editor> string can include '%f' for the filename, '%n' for
-                                  the line number and '%%' for a literal '%'.  If no '%' is used '+%n %f' is added to
-                                  the given command.
-  --tempdir <directory>         : Use given existing directory for temporary files.
-  --help, -h                    : Print this help and quit.
-
- Long option can be shorten as long the are still unique.  Short options can be combined.
- If the option 'environment', 'before' and 'after' are used toegether the
- produced code will be inserted in the given order (reversed order for 'after').
- (M) = This option can be given multiple times.
- (L) = LaTeX only. Requires the packages 'filehook' and 'currfile'.
-
-Examples:
-Show the definition of '\chapter' with different classes ('article' (default), 'book' and 'scrbook'):
-
-    latexdef chapter
-    latexdef -c book chapter
-    latexdef -c scrbook chapter
-
-Show value of `\textwidth` with different class options:
-
-    latexdef -c [a4paper]{book} -v paperwidth
-    latexdef -c [letter]{book}  -v paperwidth
-
-Show definition of TikZ's '\draw' outside and inside a 'tikzpicture' environment:
-
-    latexdef -p tikz draw
-    latexdef -p tikz --env tikzpicture draw
-
-Show definition of TikZ's '\draw' inside a node, inside a 'beamer' frame in 'handout' mode:
-
-    latexdef -c [handout]beamer -p tikz --env frame --env tikzpicture -b '\node {' -a '};' draw
-
-List all user level command sequences (macros) defined by the 'xspace' LaTeX package:
-
-    latexdef -l -p xspace
-
