Various handy shell scripts for use with Snogray renderer. runsnog Run snogray with the given args, and write an additional ".snlog" file containing some meta-data (command-line args etc) and a transcript of the run. Has special support for restarting an aborted run. The .snlog file will have the same basename (and directory) as the output image file. runcmpsnogs Run two different versions of snogray multiple times with the same arguments, using "runsnog" to record the runs into .snlog files. "sumsnoglog" can then be used on the resulting .snlog files to produce a summary of the average execution times for both. sumsnoglog Analyze .snlog files produced by "runsnog" (maybe indirectly via runcmpsnogs), and produce a summary of the average execution times (broken down by "tag", and into loading, rendering, etc, times).
