Unfortunately, no.  There is no built-in help (or any other option
parsing, for that matter, yet).  Right now, the only docu is in

IMO, the highest priority new "features" are:

  1. command line option parsing, esp. --help/-h/-?
  2. 'mingw-get uninstall a-package-specification'
  3. 'mingw-get upgrade a-package-specification' (this is just
     "uninstall what I have and install the latest, if newer; otherwise
     do nothing" so it's almost free once #2 is implemented.
  4. rpm-like query functions:
      -q -l <package-spec>   (list files in this installed package)
      -q -i <package-spec>   (tell me about this package )
      -q <package-spec>      (tell me whether this package is
                              installed, and what version it is)
      -q -a                  (list all of the packages I have installed)
     Now, we don't HAVE to follow the rather cryptic rpm command line
     interface, but I figure most folks are familiar enough with rpm
     that it's real clear what functionality I'm talking about.
  5. manifest query functions:
       list all the packages (and their versions) I *could* install

Patches Gratefully Considered...

Well, the executable didn't get erased. It just got renamed (and it is a
known issue -- I guess I need to open a tracker item):

The idea is that each of the various subcomponents -- dll packages, bin
packages, devel packages -- are ALL covered by the same license. Rather
than ship the license multiple times with each subcomponent (which would
really complicate our installed-file database), we put the relevant
files into a -lic component instead.

All of the manifests have two special markers, for every package:

      <licence tarname="libarchive-%-msys-%-lic.tar" />
      <source tarname="libarchive-%-msys-%-src.tar" />

using these -- eventually -- mingw-get should be able to figure out what
tarball contains the license file associated with what component (and
no, it can't just figure it out from the package name; for instance, the

   <package name="msys-bsdtar" ...>

does NOT have a license file in "bsdtar-*-msys-*-lic.tar" -- because
"bsdtar" is actually built from the libarchive source tarball:

   <package name="msys-bsdtar" ...>
      <licence tarname="libarchive-%-msys-%-lic.tar" />
      <source tarname="libarchive-%-msys-%-src.tar" />
      <component class="bin">
        <release tarname="bsdtar-2.8.3-1-msys-1.0.13-bin.tar.lzma" >
          <requires eq="msys-libarchive-%-msys-%-dll-2.tar" />

IMO, eventually mingw-get will *automatically* and *always* install the
associated -lic package for everything it installs.  But it doesn't do
that yet.

> [2] http://www.gnu.org/licenses/gpl-faq.html#WhyMustIInclude

We provide the license in downloadable form (specifically in EXACTLY the
same form that every other component of the package is provided in,
installable by our mingw-get installer -- it's not like we require the
end user to go troll thru the -src package or something).  We just don't
(yet) *force* the user to download it.  Eventually, we probably will...
