Hello,

Firstly many thanks to all who have worked on the git migration and also
for the offer of help :-)

I'm seeking a little advice on an efficient way to combine the gm2 git
repro with the gcc git repro.  When gcc was using subversion I had a
script which untared the gm2 git over the subversion, applied local
patches to the gcc tree and then it was ready for use.  I could git diff
in the gm2 tree and svn diff in the gcc tree - etc.

I wonder if a similar model can be achieved now gcc uses git?

In essence the gm2 front end adds three subtrees to gcc

    libgm2
    
    gcc/m2
    
    gcc/testsuite/gm2

currently these are all in one repro
gm2/gcc-versionno/{libgm2,gcc/m2,gcc/testsuite/gm2}.

http://git.savannah.gnu.org/cgit/gm2.git/tree

I'm a little cautious of choosing an initial working model without
knowing the implications.  There seem to be many possible solutions
(subtree, submodule) to name but two.

Disk space is not a concern, the time to recreate a working tree is more
important.

regards,
Gaius
