*: make GNU licensing statement forms more regular This change retains "or later" state! No licensing _changes_ here, only form is adjusted (article, space between "GPL" and "v2" and so on).

Fix tar -j support Use the old fork() method of tar compression support, rather than read_bz2.... - (uncompress)(int in, int out) seems like a more natural interface for compression code. - it might improve performance by seperating the work into one cpu bound and one io bound process. - There is extra code required to do read_[gz\|bunzip] since (uncompress)(int in, int out) will normally be used by the standalone compression applet. There have been problems with this method so if you see a "Short read" error let me know. 2003-11-05 04:55:58 +00:00			`/* Can only do one file at a time */`
