  96 This builds Koha deb packages, from a git snapshot. It's not suitable for
  97 making upstreamable verions, but handy for your own local packages.
  98
  99 Options:
 100     --buildresult, -r
 101         the location that the resulting .deb, .changes, etc. will be placed in.
 102         Default is whatever pdebuild uses.
 103     --distribution, -D
 104         the distribution value to set in the changelog when editing it. Default
 105         is 'squeeze-dev'.
 106     --git-checks, -g
 107         what level of git checks are run to determine if the working copy is
 108         clean enough. One of 'all' (any changes are bad), 'modified' (only
 109         tracked files with untracked changes will cause an error), and 'none'
 110         (checking git status is skipped totally.) Default is 'all'.
 111     --version, -v
 112         the version string for the resulting package. Default is '$version'.
 113     --(no)autoversion
 114         whether or not to use the date and git commit ID in the version value.
 115         Default is to include it.
 116     --debug, -d
