# How to build a Subversion distribution tarball:
#
# Run this script in the top-level of a configured working copy that
# has apr, apr-util, and neon subdirs, and you'll end up with
# subversion-rXXX.tar.gz in that top-level directory.
#
# Unless specified otherwise (with a single REVISION argument to this
# script), the tarball will be based on the HEAD of the repository.
#
# It will *not* be based on whatever set of revisions are in your
# working copy.  However, since 
#
#   - the documentation will be produced by running "make doc" 
#     on your working copy's revisions of the doc master files, and
#
#   - since the APR and APRUTIL trees are basically copied from your working 
#     copy, 
#
# it's probably simplest if you just make sure your working copy is at
# the same revision as that of the distribution you are trying to
# create.  Then you won't get any unexpected results.

The old CVS ChangeLog is kept at

If you want to see changes since Subversion went self-hosting,
you probably want to use the "svn log" command -- and if it 
does not do what you need, please send in a patch!
