Well, the holidays are long over and I haven't updated msqur.com in a while. I'm adding some configuration management to it, so nothing visible will happen for a while. What's planned, however, is .ini file parsing so that .msq files can be parsed according to the INI file version they use. That is, I will parse the INI file for the schema to a .msq file instead of hardcoding it. This way showing a .msq from a new code version is just a .ini file upload away.
INI file parsing shouldn't take long. PHP has exactly what I need (literally:
parse_ini_file()), but I'll have to bake my own slightly modified version since the MS format isn't standard-if there even is a standard for INI files.
