+Usage (from gitolite clone directory):
+
+    ./install
+        to run gitolite using an absolute or relative path, for example
+        'src/gitolite' or '/full/path/to/this/dir/src/gitolite'
+
+    ./install -ln [<dir>]
+        to symlink just the gitolite executable to some <dir> that is in
+        $PATH.  <dir> defaults to $HOME/bin if <dir> not specified.  <dir> is
+        assumed to exist; gitolite will not create it.
+
+        Please provide a full path, not a relative path.
+
+    ./install -to <dir>
+        to copy the entire 'src' directory to <dir>.  If <dir> is not in
+        $PATH, use the full path to run gitolite commands.
+
+        Please provide a full path, not a relative path.
+
+    <perl-executable> ./install -to <dir>
+        to copy the entire 'src' directory to <dir>, but will replace
+        all of the shebangs with the path to <perl-executable>.  This
+        is a way to force gitolite to use some perl that is not
+        installed at /usr/bin/perl.
+
+Simplest use, if $HOME/bin exists and is in $PATH, is:
+
+    git clone https://github.com/sitaramc/gitolite
+    gitolite/install -ln
+
+    # now run setup
+    gitolite setup -pk /path/to/YourName.pub
