## TO MAKE THIS RUN YOUR CUSTOM COMPILED SVN, two simple options:
## 1. Adjust your PATH to point at your custom installed location:
##      export PATH="$HOME/prefix/svn_trunk/bin:$PATH"
## OR
## 2. Uncomment the four lines below to use aliases into your
##    built source tree. The next line is the only line you should
##    need to adjust.
# SVNDIR=/path/to/built_subversion_source_tree
# function svn() { "$SVNDIR/subversion/svn/svn" "$@"; }
# function svnserve() { "$SVNDIR/subversion/svnserve/svnserve" "$@"; }
# function svnadmin() { "$SVNDIR/subversion/svnadmin/svnadmin" "$@"; }
