This program is part of Netpbm.
ymtopbm reads a file acceptable to the face and xbm programs by Bennet Yee (bsy+@cs.cmu.edu). and writes a PBM image as output.
There are no command line options defined specifically for ybmtopbm, but it recognizes the options common to all programs based on libnetpbm (See Common Options.)
