a2ping: convert image and vector graphics to compatible EPS and PDF

a2ping is a UNIX command line utility written in Perl that converts many
raster image and vector graphics formats to EPS or PDF and other page
description formats. Accepted input file formats are: PS (PostScript), EPS,
PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX, TGA. Accepted output 
formats are: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM, PS, markedEPS, markedPS, 
PNG, XWD, BMP, TIFF, JPEG, GIF, XPM. a2ping delegates the low-level 
work to Ghostscript (GS), pdftops and sam2p. a2ping fixes many glitches 
during the EPS to EPS conversion, so its output is often more compatible 
and better embeddable than its input.

Installation: copy the file a2ping.pl to a2ping on your $PATH.
