OS/2 script doing a kind of 'make' on a TeX file. First the TeX
source if TeXed until the .aux-file stays constant. Then, if
the -p option is provided, the postscript file is generated.
No action is taken, when the file to create is more recent than
the corresponding source from which it is to create.
NOTE: The argument must be given without extension!
The -p option tells texit, that the resulting DVI file should be
processed by dvips afterwards.
First get out the basename of the file and the path where it is located
