Vadim Zeitlin 3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.

If nothing else, this will make an eventual transition to Git simpler.

Closes #14487.

// wxCmdLineParser is a class for parsing command line.
//
// It has the following features:
//
// 1. distinguishes options, switches and parameters; allows option grouping
// 2. allows both short and long options
// 3. automatically generates the usage message from the cmd line description
// 4. does type checks on the options values (number, date, ...)
//
// To use it you should:
//
// 1. construct it giving it the cmd line to parse and optionally its desc
// 2. construct the cmd line description using AddXXX() if not done in (1)
// 3. call Parse()
// 4. use GetXXX() to retrieve the parsed info
