Subversion prompt is a bash script that provide an easy way to modify your bash prompt to add information about the subversion state of the current directory.
To use it, add something like that to your .bashrc :
SVNP_HUGE_REPO_EXCLUDE_PATH="nufw-svn$|/tags$|/branches$"
. ~/bin/subversion-prompt
# set a fancy prompt
PS1='\u@\h:\w$(__svn_stat)\$ '
See in documentation included in the script.
