put the VERSION file in the right place

I don't know why I had put VERSION in GL_ADMIN_BASE, which is pretty
stupid.  It should be in GL_BINDIR.

It also has nothing to do with setup -- the file needs to be generated
at 'install' time.

-1.  Clone the repo and copy src somewhere (or leave it where it is, if you're
-    sure no one will 'git pull' on a running system!)

-2.  (Optional) Make a symlink for the single executable 'gitolite' to

+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> defauls to $HOME/bin if <dir> not specified.
+    ./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.
+
+Simplest use, if you have $HOME/bin in $PATH, is:
+
+    git clone -b g3 git://github.com/sitaramc/gitolite
+    gitolite/install -ln
+
+    # now run setup
+    gitolite setup -pk /path/to/YourName.pub
