[Wvware-devel] "wrapper" fixes for wvware-0.6.4

[Michal J. <mi...@ha...>]

In my attempt to make vmware to do something more useful for me
I made various "peripheral" changes.  First I made sure that
generated LaTeX files are using Type1 fonts as this makes quite
a bit difference later on for Postscript and PDF.

I also rewrote various auxilliary scripts to make them safer
(temporary files handling), more robust in a face of error conditions
and not to leave junk around in failures, and to supply default
output files if not specified explicitely.  Moreover a conversion
to PDF works using 'pdflatex' instead of Adobe-only 'distill'.

Modified scripts rely explicitely on "bash-ism".  Probably the biggest
one is: 'name=${1%\.*}'.  If you prefer to keep these "bash-free",
and some shells do not support such pattern substitution,
then this construct can be replaced by something like that

    name=`echo $1 | sed 's/\.[^.][^.]*$//'`

and few instances of more readable '...=$(...)' can be made into backquotes.
Probably the most troublesome is 'shopt -s nullglob' in make_epses.sh.
A possible replacement is something along these lines:

   list=`echo ${1}*.wmf`
   if [ "$list" != "${1}"'*.wmf' ] ; then
      for i in $list ; do
       ....
      done
   fi

but this may fail with some patterns (when there is a file $1'*.wmf', for
example) although it should work well enough in practice.

Originals were torn between using 'which' and 'type' to check for
programs existence.  I changed them consistently to 'type'.  Actually
'type --path ...' would be even better but this is bash again.

A documentation was NOT modified to reflect that output file names
are now allowed but not required.  This should be done if fixes, or
something similar, would be accepted.

Makefile for version 0.6.4 has some forgotten leftovers from previous
versions.

I attach a tar.gz archive with all these patches.  It includes also
an rpm spec file which is a modified spec from Red Hat Powertools
distribution.  Use as you see fit.
