# Reports number of commits from the commits logs.
# The previous version just use `git log` but that doesn't span different projects
# and last week I messed up and made too many commits.
# Now my stats are ugly :(

# 2024-02-13
# Allow for a numeric argument that selects the number of days to show
#  commits for. This is useful when I want to look further back.

# 2024-01-29
# Move it to the git scripts repo, don't hardcode the scripts repo's name.

# 2024-01-23
# Fixed the fact that it wasn't counting the number of GH actions well.

# 2023-01-02
# Fixed date handling so that we'll be grepping for the year of the commit,
#  not the current year.

# 2022-08-30
# Added a loop around this to show commits for the last few dates in the
#  commit logs, because I'm often not committing as today.

# This is a very, very elaborate way to get the most recent two dates from the
#  different commit logs. We need to do this, because there could be an old
#  commit log, and there we need to properly sort the dates.
