Add `trunk/Manuals/Distro' directory.
- In this directory we maintain distribution-specific
documentation like, release notes, eula, web browser's default
page, Apache test page and similar stuff.
- To produce manuals in this directory, you need to provide the
option `--releasever' to specify the release information you
want to produce these manuals for. You can produce them all or
just few of them using the option `--filter'.
- Remember: Don't version output content produced in this
directory. Only source files are versioned (i.e., the docbook
files only).
