20 * This module implements AIX-specific printcap loading. Most of the code
21 * here was originally provided by Jean-Pierre.Boulard@univ-rennes1.fr in
22 * the Samba 1.9.14 release, and was formerly contained in pcap.c. It has
23 * been moved here and condensed as part of a larger effort to clean up and
24 * simplify the printcap code. -- Rob Foehl, 2004/12/06
