The SPR (Spray) file format is Pangya's animation scripting format, used to define particle based animations which then are used in
.seq files to create animation loops.
SPR files are relatively simply structured, containing a line-spanning command. Some quirk about their syntax, commented lines start with
;, so those shouldn't be interpreted.
Calls to commands follow this structure:
[command] = [comma-separated arguments, parenthesis-wrapped lists]
