Since these will be printed on real dead paper and sent out in the
world, it seems like it may be a very good idea if we can identify what
version they were built from.
Without this it looks a little bare. Note that this is not an actual
heading, because otherwise the Table of Contents will appear in itself,
which is weird.
By setting the `role=bare` property on these links, the URLs do not get
included in the text of the print PDFs. While we want to include the
URLs for most links, in some cases it doesn't add anything and is just
disruptive to the flow of the text.
When uploading to Lulu.com an error was being produced, and with some
experimentation I discovered it was due to the `[%always]` tag used to
force page breaks; removing it fixes the problem. To ensure the Table of
Contents appears on the right page, I added a small amount of copyright
blurb to page 2.
Since we want this to become an actual book, we need the generated PDF
to properly look like one. This required a bit of Asciidoc mangling but
mostly looks right.
The following changes should make the manual more available, and easier
to understand:
1) "make dist" and "make install" will now include all translations of
the manual.
1) A "freedoom-" prefix will be used in all cases in place of just
"manual".
2) All languages will have a two letter suffix, so English is now
"-en".
3) Only the PDF specified will be built when invoked in the top level
directory. For example:
make manual/freedoom-manual-en.pdf
