All of those features are available in hg, darcs, and other dscm tools.

But to get back on topic, unless I’ve overlooked a contrib package somewhere, how about we begin with the requirements to get a fully working git installed on Plan 9.  For example,

## the dependencies required for git on a bare-bones FreeBSD install:
# pkg install git
Updating FreeBSD repository catalogue...
FreeBSD repository is up-to-date.
All repositories are up-to-date.
The following 18 packages will be affected (of 0 checked):

New packages to be INSTALLED:
        git: 2.3.4
        expat: 2.1.0_2
        p5-Authen-SASL: 2.16_1
        p5-GSSAPI: 0.28_1
        perl5: 5.18.4_11
        p5-Digest-HMAC: 1.03_1
        p5-Net-SMTP-SSL: 1.01_3
        p5-IO-Socket-SSL: 2.012
        p5-Mozilla-CA: 20141217
        p5-Net-SSLeay: 1.68
        p5-Socket: 2.018
        p5-IO-Socket-IP: 0.37
        python27: 2.7.9
        libffi: 3.2.1
        p5-Error: 0.17023
        curl: 7.41.0
        ca_root_nss: 3.18
        cvsps: 2.1_1



I’m not sure what cvsps is for, that seems to have cropped up on the fbsd pkg sometime between git versions 2.3.1 and 2.3.4.  It’s been years^wdecades since I’ve tinkered with perl, and I’m fairly certain the perl 5.8 version available on Plan 9 won’t support the modules included in the above list.  So Plan 9 needs a modern perl to run git effectively with specific attention to the additional modules.  Expat is the “eXpat XML parser library”.  Libffi is something maintained on sources.redhat.com.  Many of those modules depend on OpenSSL, so add that to the list.  It’s also possible a recent port of bash will also be required as the git support scripts may not work with our ape/sh or ape/psh.  We’ve got python 2.7.8 [.9 soon] covered.  

Piece of cake, all that should fit on a coaster.
