On Sat, 30 Apr 2005, Harald Harders submitted a new package called
gefileversion
Location on CTAN: support/getfileversion/ License: LPPL
From the README:
This simple shell script prints the version and date of a LaTeX class or style file.
Syntax: getfileversion <file>
This programme handles style files (extension .sty) and class files (extension .cls). If no extension is given, .sty is assumed.
This is the initial version v0.1.
Thanks for the submission.
