<p>This is a sample program that is similar to "git init". See the
documentation for that (try "git help init") to understand what this
program is emulating.</p>
<p>This demonstrates using the libgit2 APIs to initialize a new repository.</p>
<p>This also contains a special additional option that regular "git init"
does not support which is "--initial-commit" to make a first empty commit.
That is demonstrated in the "create<em>initial</em>commit" helper function.</p>
