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 diff driver, the
       symlinks  to annexed files are not set up right, so the external diff 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  this,  you  will  need  to have installed some git external diff driver command. This is not the
       regular diff command; it takes a git-specific input. See git's  documentation  of  GIT_EXTERNAL_DIFF  and
       gitattributes(5)'s documentation of external diff drivers.

       Configure  git  to  use "git-annex diffdriver -- cmd params --" as the external diff driver, where cmd is
       the external diff driver you want it to run, 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 --
