Version Control With Subversion Source

Use long subcommand names. Patch by me. Reminder by Larry Shatzer. :-)

Use long subcommand names. Patch by Larry Shatzer <fugazi@...>.

Fix some misaligned XML, and cmpilato-ify the svnserve stuffs.

* ch05.xml (svnserve): reorganize and simplify, at the suggestions of
ghudson.

Lots more book stuff.

* appb.xml: new appendix documenting cvs2svn.py, to some small degree.

* rcsparse.py: added to cvs2svn/ dir, so people can stop asking where
to get it! please!

* appa.xml (Binary files): add internal binary-diff explanation.

* ch05.xml: expand our explanation of how to run svnserve, and how to
set up ssh tunneling. Also, add a honest comparison of
reasons to run either mod_dav_svn or svnserve.

* ch06.xml (Servers): uncomment the 'svn-tunnel-agent' documentation.

* ch07.xml (RA-SVN): add one more paragraph.

Note to self: Sleep is not optional.

* doc/book/book/appe.xml: Had it the wrong way around.

Abstractify Fitz's new optional xsltproc options.

Fix an awkward phrasing.

Use <literal> for request types, not <command>.

Why the quotes? People call it "svnserve" because it *is* svnserve.
