ATTRIBUTION — the d/BASIC conformance corpus

The 96 listings in this directory are the BASIC programs of David H. Ahl's
"BASIC Computer Games" (Creative Computing, 1978), as transcribed and maintained
by the coding-horror/basic-computer-games project and dedicated to the public
domain by that project's contributors under the Unlicense (LICENSE.txt).

  provenance   PROVENANCE.json — upstream path, byte count and sha256, one row
               per listing

What was selected
  Every top-level NN_ game directory of the upstream repository except the
  three infrastructure directories (00_Alternate_Languages, 00_Common,
  00_Utilities): 96 games. One root .bas per game, chosen by shortest
  basename. Each listing is reproduced byte-for-byte; only the file name
  changed (01_Acey_Ducey/aceyducey.bas became 01_Acey_Ducey.bas), and
  PROVENANCE.json records the original path for every one.
