The extensions did mostly cover -dnl a portable definition of filenames and such stuff. - -dnl The most interesting thing however is that the opengroup (the. -dnl UNIX standardization body) did not document the tool for the -dnl portable tar format under the name of "tar" but instead it did -dnl use the name "pax" which stands for "portable archiver". Even -dnl more so, the "pax" utitility is required to understand the old -dnl tar and cpio formats but it will default to a "tar"-like variant. -dnl The "pax" tool has been in the Unix standard ever since UNIX92. -dnl -dnl Interestingly gnu-tar will use the pax features as soon as they -dnl are required - but you can not be sure if gnu-tar is available, -dnl and it is quite likely that the system tar will default to the -dnl old format of the system in whatever it was. On any currrent -dnl Unix system however one should be able to find "pax", so one -dnl should prefer that one as the most portable tool. - -dnl The downside is however that the commandline options of "pax" -dnl are different from "tar"/"gtar". That's why we define two -dnl subst'ed names here - PAX_TAR_CREATE and PAX_TAR_EXTRACT, For -dnl extra portability the first argument should be "*.tar" file -dnl name but you should be aware that in most cases the "pax" tool -dnl is invoked. Nota bene: do not use "*.pax" as the file name -dnl extension because some file managers interpret it as a TeX file. -dnl -dnl @category C -dnl @author Guido U.
