+#:  * `unpack` [`--git`|`--patch`] [`--destdir=`<path>] <formulae>:
+#:    Unpack the source files for <formulae> into subdirectories of the current
+#:    working directory. If `--destdir=`<path> is given, the subdirectories will
+#:    be created in the directory named by `<path>` instead.
+#:
+#:    If `--patch` is passed, patches for <formulae> will be applied to the
+#:    unpacked source.
+#:
+#:    If `--git` is passed, a Git repository will be initalized in the unpacked
+#:    source. This is useful for creating patches for the software.
