Splint

Splint is a file compression utility, and associated file format, developed by Kenji Rikitake and Naoshi Wakatabe.

Identifiers
DOS versions of Splint use file extension .spl. Unix versions append .sp to the original filename.

Identification
Files begin with signature bytes. The next byte, named "STYLE_ID" in the source code, is always  in Splint v2.1.
