### DESCRIPTION:
### This script transforms dvi-files to pdf-files using dvihps and ghostscripts pdfwriter
### It has been tested with emtex's dvips and ghostscript 4.01 on WindowsNT
### Usage: dvi2pdf <options>
### where <options> are the usual dvips options and/or one of the following ones
### -nopdf produce only the ps-file not the pdf-file
### (this option is automatically used if output file has suffix .ps)
### -noborder produces an outputfile where the hyper-links don't have borders
### -s<x>,<y> shifts the hyper-links by (<x>,<y>)
#Note: This script overwrites eventually existing files named
# $$.ps, $pdffile.ps, $pdffile.pdf
# where $$ is the process id (as provided by perl)
# and $pdffile is the output file name given with the option -o or
# derived from the input file name, i.e. the input file name without suffix
### CONFIGURATION:
#Access paths for the programs dvihps and ghostscript
$GHOSTSCRIPT = "gswin32c"; #how to call ghostscript
$DVIHPS = "dvips"; #how to call hyper postscript capable dvips
$REMOVEFILE = "del"; #command to delete file
### Probably no changes necessary below this line
