Gource multi repo script

#!/usr/bin/env bash
# Generates gource video (h.264) out of multiple repositories.
# Pass the repositories in command line arguments.
# Example:
# <this.sh> /path/to/repo1 /path/to/repo2
# 960x540 is youtube resolution
RESOLUTION="960x540"
outfile="gource.mp4"

	# 1. Generate a Gource custom log files for each repo. This can be facilitated by the --output-custom-log FILE option of Gource as of 0.29:
	logfile="$(mktemp /tmp/gource.XXXXXX)"
	gource --output-custom-log "${logfile}" ${repo}
	# 2. If you want each repo to appear on a separate branch instead of merged onto each other (which might also look interesting), you can use a 'sed' regular expression to add an extra parent directory to the path of the files in each project:
	gsed -i -E "s#(.+)\|#\1|/${repo}#" ${logfile}
# using gnu sed on mac, on linux "sed" should work
	logs[$i]=$logfile
	let i=$i+1
