SYNOPSIS

       diffman-git [diff-options ...] [[base-commit] commit]

       The  diffman-git  command  formats  a  manual  page  at  two git(1) commits, and then runs diff(1) on the
       formatted outputs.

       If the commit is not specified, it diffs the working directory against HEAD.

       If the base-commit is not specified, the comparison is done against the previous commit.

OPTIONS

       -Un    output n (default 3) lines of unified context.

       -w     Ignore all white space.
