Rather than guess user's intention based on whether --prefix was
specified, use an explicit option to enable strict GNU Coding Standards
for installation directories.
The default is to use /etc and /var rather than corresponding directories
under prefix.
Use --enable-strict-locations in "make distcheck", it expects all
installed files to be under prefix.
Since libpainter is going to become a subpackage, we can make librfxcodec
a subpackage as well.
With this change, librfxcodec is configured, built and linked to xrdp
automatically if enabled by "--enable-rfxcodec"
librfxcodec is packaged by "make dist" regardless of "--enable-rfxcodec"
librfxcodec/confgure is run unconditionally, it's needed for "make dist"
to work. But librfxcodec is only compiled if enabled.
Markdown is easily readable in text editors. Unlike ODT, markdown can be
patched. GitHub shows markdown with pretty formatting.
Remove bad examples. Improve explanations for good examples.
Use Unicode finger sign to work around the issue of code block after a
list.
Make coding_style.md distributable.
"make distcheck" sets prefix to a user-owned directory, compiles code and
runs "make install". That fails if systemd files need to be installed, as
their location if not relative to the prefix.
Keeping separate files is more maintainable than merging them into a
single aclocal.m4 file. It is easier for users to understand where those
files come from.
Automake knows how to distribute files in the m4 directory.
