<literal>remotes/</literal> directory. This makes the target repo
suitable to be exported for other clients to pull from as an ostree
remote. If no specific refs are specified, all refs will be fetched (the
remote must have a summary file present).

<title>Description</title>
<para>
Without --mirror, this command will create new refs
under <literal>remotes/REMOTE/</literal> directory
for each pulled branch unless they are already created. Such
refs can be then referenced by <literal>REMOTE:BRANCH</literal> in
<literal>ostree</literal> subcommands (e.g. <literal>ostree log origin:exampleos/x86_64/standard</literal>).
</para>
<para>
This command can retrieve just a specific commit, or go all
the way to performing a full mirror of the remote
repository. If no <literal>BRANCH</literal> is specified,
all configured branches are retrieved.
</para>
<para>
A special syntax in the <literal>@</literal> character allows
specifying a specific commit to retrieve from a branch. The
use cases for this are somewhat similar to pulling a specific
git tag; one could e.g. script a system upgrade to a known-good
version, rather than the latest from the content provider.
</para>

<title>Example</title>
<para><command>$ ostree --repo=repo pull --depth=-1 --mirror remote_name</command></para>
<para>Perform a complete mirror of the remote. (This is
likely most useful if your repository is also
<literal>archive</literal> mode)</para>
<para><command>$ ostree --repo=repo pull remote_name exampleos/x86_64/standard</command></para>
<para>Fetch the most recent commit to <literal>exampleos/x86_64/standard</literal>.</para>
<para><command>$ ostree --repo=repo pull remote_name exampleos/x86_64/standard@98ea6e4f216f2fb4b69fff9b3a44842c38686ca685f3f55dc48c5d3fb1107be4</command></para>
<para>Download the specific commit starting with
<literal>98ea6e</literal> as if it was the latest commit for
<literal>exampleos/x86_64/standard</literal>.</para>
