<title>DESCRIPTION</title>
<para>
&git-dch; reads git commit messages and generates the Debian changelog from
it. If no arguments are given &git-dch; starts from the last tagged Debian
package version up to the current tip of the current branch. If the
distribution of the topmost section in
<filename>debian/changelog</filename> is <emphasis>UNRELEASED</emphasis>
the changelog entries will be inserted into this section. Otherwise a new
section will be created.</para>
<para>If <option>--auto</option> is given &git-dch; tries to guess the
last &git; commit documented in the changelog - this only works in snapshot
mode. Otherwise <option>--since</option> can be used to tell &git-dch;
at which point it should start in the &git; history.</para>
<para>
The additional path arguments can be used to restrict the repository paths
&git-dch; looks at. Setting <replaceable>path</replaceable> to
<emphasis>debian/</emphasis> is a good choice if upstream uses &git; and
all Debian packaging changes are restricted to the
<replaceable>debian/</replaceable> subdir. In more sophisticated cases
(like backports) you can use <option>--git-log</option> to restrict the
generated changelog entries further. E.g. by using
<option>--git-log=</option><replaceable>"--author=Foo Bar"</replaceable>.</para>

<title>Snapshot mode</title>
<para>
Snapshot mode can be used for quick test and install cycles without
having to worry about version numbers or changelog entries.
</para><para>
When using <option>--snapshot</option> or <option>-S</option> &git-dch;
uses a pseudo header in the Debian changelog to remember the last git
commit it added a changelog entry for. It also sets a version number
ending in
<replaceable>~<snaspshotnumber>.gbp<commitid></replaceable>.
It automatically increments the snapshot number on subsequent invocations
of &git-dch; <option>-S</option> so that later snapshots automatically
have a higher version number. To leave snapshot mode invoke &git-dch;
with the <option>--release</option> option. This removes the pseudo
heaader and unmangles the version number so the released version has a
higher version number than the snapshots.
