  Description     : generate side-by-side HTML diff reports for Git repositories

git-diff-html renders the differences in a Git repository as a
Gerrit/BeyondCompare-style side-by-side HTML report. It supports comparing
the working tree against HEAD or any commit, two commits against each other,
and staged changes. Reports feature line-level and character-level (inline)
diff highlighting, C/C++ syntax highlighting, a navigable file list, a
change summary, and an interactive two-pane viewer with draggable splitters
and synchronized horizontal scrolling. The report is a single self-contained
HTML file.

I am the upstream author. A complete Debian packaging directory is included
in the upstream repository.
