+    '''create an unversioned archive of a repository revision with some keywords expanded
+
+    By default, the revision used is the parent of the working
+    directory; use -r/--rev to specify a different revision.
+
+    The archive type is automatically detected based on file
+    extension (to override, use -t/--type).
+
+    .. container:: verbose
+
+      Examples:
+
+      - create a zip file containing the 1.0 release::
+
+          hg archive -r 1.0 project-1.0.zip
+
+      - create a tarball excluding .hg files::
+
+          hg archive project.tar.gz -X ".hg*"
+
+    Valid types are:
+
+    :``files``: a directory full of files (default)
+    :``tar``:   tar archive, uncompressed
+    :``tbz2``:  tar archive, compressed using bzip2
+    :``tgz``:   tar archive, compressed using gzip
+    :``uzip``:  zip archive, uncompressed
+    :``zip``:   zip archive, compressed using deflate
+
+    The exact name of the destination archive or directory is given
+    using a format string; see :hg:`help export` for details.
+
+    Each member added to an archive file has a directory prefix
+    prepended. Use -p/--prefix to specify a format string for the
+    prefix. The default is the basename of the archive, with suffixes
+    removed.
+
+    Returns 0 on success.
