[Prafulla Giri <pratheblackdiamond@gmail.com>]

[-- Attachment #1.1: Type: text/plain, Size: 407 bytes --]

Esteemed maintainers,

Attached are two patches to update the package git-lfs in
gnu/packages/version-control.scm.

Patch0001 - adds two new phases to build and install man pages into the
user's GUIX_PROFILE. This makes the git-lfs man pages available. `man
git-lfs` have hitherto thrown "No manual entry for git-lfs". This patch
fixes it.

Patch0002 - Upgrades package git-lfs to version 2.11.0

Thank you
