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 --
