#: * `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` (or `-g`) is passed, a Git repository will be initialized in the unpacked
|
|
#: source. This is useful for creating patches for the software.
