NAME

       git-annex-diffdriver - external git diff driver shim

SYNOPSIS

       git annex diffdriver -- cmd --opts --

DESCRIPTION

       This  is  an external git diff driver shim. Normally, when using git diff with an external
       git driver, the symlinks to annexed files are not set up right, so the external git driver
       cannot  read  them in order to perform smart diffing of their contents. This command works
       around the problem, by passing the fixed up files to the real external diff driver.

       To use, just configure git to use "git-annex diffdriver -- cmd params --" as the  external
       diff  command, where cmd is the real external diff command you want to use, and params are
       any extra parameters to pass to it. Note the trailing "--", which is required.

       For example, set GIT_EXTERNAL_DIFF=git-annex diffdriver -- j-c-diff --
