-
- extar.c: a tar extractor for Unix which knows about RISC OS filenames.
-
- You can control its handling of filenames by setting two environment
- variables:
-
- ARCSWAP
- This contains a colon separated list of directory names which should be
- swapped for files. That sentence probably doesn't make much sense, so
- here's an example:
-
- If ARCSWAP = "c:s:tmp" then
-
- RISC OS Unix
- ======= ====
- wibble.c.fred -> wibble/fred.c
- tmp.wibble -> wibble.tmp
- s.fred -> fred.s
-
- The default value (you can change it in the sources) is
-
- ARCSWAP="a:c:f:h:i:l:o:p:s:y:w:vim:info"
-
- ARCDOT
- This contains a colon separated list of filenames which should be
- combined with their directory name to make a dot-extension. This is used
- mainly by *TeX. Again, an example makes it clearer (I hope):
-
- If ARCDOT = "tex:dvi:eps" then
-
- RISC OS Unix
- ======= ====
- wibble.fred.tex -> wibble/fred.tex
- fred.dvi -> fred.dvi
- wibble.fred.eps -> wibble/fred.eps
-
- The default value (again specified in the sources) is
-
- ARCDOT="txt:tex:dvi:eps:ps:bib:sty:bst:log:blg:aux:bbl:lof:lot:toc"
-
- Nothing in the sources requires anything more complex than an ANSI C
- compiler, plus the "mkdir" system call. So it should compile on any Unix.
- I also use it regularly on Windows NT.
-
- If you have any questions or bug fixes, please let me know.
