tools/dev/bash_completion

# Programmable completion for the Subversion svn command under bash. Source
# this file (or on some systems add it to ~/.bash_completion and start a new
# shell) and bash's completion mechanism will know all about svn's options!
# Who wants to read man pages/help text...

# Doesn't do --xml-file and its associated options, that's intentional :)

# Known to work with bash 2.05a with programmable completion and extended
# pattern matching enabled (use 'shopt -s extglob progcomp' to enable
# these if they are not already enabled).
