As stated in doc/README, contributions from now on should be under
"GPLv2 or older" to allow upgrading to newer versions of GPL
(if I think they are sensible :-)

This is essentially the same as "GPLv2 or older approved by the author."

Feedback is welcome.

Added in a01045f2480a21f28dd90e278b4f560020a97b9e.

Removed unneeded pass statements and done TODO tags.

The command being run will be shown first, and then prefixed with the
running time after it has been completed.

By default 'gnuplot' will be searched from the system path.

On unix, when "shell = False" (default), the args must be a list of
args. While on Windows, filling args with a list causes problems. As a
trade-off, set the this flag and using a string as the command, although
this might sacrifice some performance, but that's not the main concern
in this script.

- git-rev-list: use %T instead of %H
- git-ls-tree: added --name-only

This is a workaround for linux-2.6 repository.

Any additional statistics based on the extracted data should be produced in it.

Only names are shown for the next 5.

Thanks to Alexander Botero-Lowry.

This should make gitstats work on FreeBSD.

This reverts "Attempt to optimize file counting." and related commits.

(commit c257429c561af8b99bb0a0daa65871a80a9fedb2)

Two executions of 'git-rev-list' were merged and python used instead of sh
snippet. From initial testing this seems to _slow_ things down.

Hopefully fixes a problem with linux-2.6 repository.

Earlier this borked on author names containing "," (or example, wine
repository). Now it will instead check for line containing "files changed,".

Removed an extra "git-rev-list".

For now it's taken from the basename of the repository path.

Get total lines of code from "git-log --shortstat" instead of "cat".

Line statistics are gathered correctly (again).
