C Adventure Toolkit

The C Adventure Toolkit ("CAT") is an interactive fiction system for MS-DOS and the Atari ST, written in 1985 by "Tony Stiles". It produces C from input files, which can then be compiled into runnable programs.

CAT has two "standard libraries": the "standard library" written in the CAT language, and the set of C sources that need to be compiled along with the generated C (in directory GENSRC.D).

Extensions
The input for a single CAT compilation consists of a number of files with extension .d (.D due to DOS naming conventions), as well as an extensionless index file named "GENLIST" (containing nothing but the filenames of .D files).

Identification
.d files will probably contain the strings "@rem", "@room", "@obj", and "@msg".
