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.

wxWidgets translator guide
==========================
This note is addressed to wxWidgets translators.
First of all, here is what you will need:
1. GNU gettext package version 0.10.35 or later (NB: earlier versions were
known to have serious bugs)
a) for Unix systems you can download gettext-0.10.tar.gz from any GNU
mirror (RPMs and DEBs are also available from the usual places)
b) for Windows you can download the precompiled binaries from
www.wxwidgets.org or install PoEdit (poedit.sourceforge.net) and
add <installdir>/poEdit/bin to your path (so it can find xgettext).
2. A way to run a program recursively on an entire directory from the command
line:
a) for Unix systems, this is done in locale/Makefile using the standard find
command and xargs which is installed on almost all modern Unices. If you
are unlucky enough to not have xargs, you can use the -exec option of find
instead.
b) for Win32 systems you can use either Cygwin or MinGW. If you don't have
those it is less trivial: if you have 4DOS/4NT/bash, that's
fine, but you'd have to use some kind of "for /s" loop with the
command.com/cmd.exe.
3. (at least read) access to the subversion is not necessary strictly speaking, but
will make things a lot easier for you and others.
Now a brief overview of the process of translations (please refer to GNU
gettext documentation for more details). It happens in several steps:
1. the strings to translate are extracted from the C++ sources using xgettext
program into a wxstd.pot file which is a "text message catalog"
2. this new wxstd.pot file (recreated each time some new text messages are added
to wxWidgets) is merged with existing translations in another .po file (for
example, de.po) and replaces this file (this is done using the program
msgmerge)
3. the resulting .po file must be translated
4. finally, msgformat must be run to produce a .mo file: "binary message catalog"
How does it happen in practice? There is a Makefile in the "locale"
directory which will do almost everything (except translations) for you. i.e.
just type "make lang.po" to create or update the message catalog for 'lang'.
Then edit the resulting lang.po and make sure that there are no empty or fuzzy
translations left (empty translations are the ones with msgstr "", fuzzy
translations are those which have the word "fuzzy" in a comment just above
them). Then type "make lang.mo" which will create the binary message catalog.
Under Windows (If you don't have Cygwin or MinGW), you should execute the
commands manually, please have a look at Makefile to see what must be done.
For platform specific translations, .po files such as 'locale/msw/it.po' can be
used to provide translations that override the usual ones in 'locale/it.po'.
The generated .mo files are then installed under the names such as 'wxmsw.mo'
alongside the generic 'wxstd.mo'.
A new platform specific translation should be added to a section such as this
in wx.bkl:
<gettext-catalogs id="locale_msw">
<srcdir>$(SRCDIR)/locale/msw</srcdir>
<catalog-name>wxmsw</catalog-name>
<linguas>it</linguas>
<install-to>$(LOCALEDIR)</install-to>
</gettext-catalogs>
