  18 Usage (from gitolite clone directory):
  19
  20     ./install
  21         to run gitolite using an absolute or relative path, for example
  22         'src/gitolite' or '/full/path/to/this/dir/src/gitolite'
  23
  24     ./install -ln [<dir>]
  25         to symlink just the gitolite executable to some <dir> that is in
  26         $PATH.  <dir> defaults to $HOME/bin if <dir> not specified.  <dir> is
  27         assumed to exist; gitolite will not create it.
  28
  29         Please provide a full path, not a relative path.
  30
  31     ./install -to <dir>
  32         to copy the entire 'src' directory to <dir>.  If <dir> is not in
  33         $PATH, use the full path to run gitolite commands.
  34
  35         Please provide a full path, not a relative path.
  36
  37 Simplest use, if $HOME/bin exists and is in $PATH, is:
  38
  39     git clone git://github.com/sitaramc/gitolite
  40     gitolite/install -ln
  41
  42     # now run setup
  43     gitolite setup -pk /path/to/YourName.pub
