/*
- * This module contains code to parse and cache printcap data, possibly
- * in concert with the CUPS/SYSV/AIX-specific code found elsewhere.
- *
- * The way this module looks at the printcap file is very simplistic.
- * Only the local printcap file is inspected (no searching of NIS
- * databases etc).
- *
- * There are assumed to be one or more printer names per record, held
- * as a set of sub-fields separated by vertical bar symbols ('|') in the
- * first field of the record. The field separator is assumed to be a colon
- * ':' and the record separator a newline.
- *
- * Lines ending with a backspace '\' are assumed to flag that the following
- * line is a continuation line so that a set of lines can be read as one
- * printcap entry.
- *
- * A line stating with a hash '#' is assumed to be a comment and is ignored
- * Comments are discarded before the record is strung together from the
- * set of continuation lines.
- *
- * Opening a pipe for "lpc status" and reading that would probably
- * be pretty effective. Code to do this already exists in the freely
- * distributable PCNFS server code.
- *
* Modified to call SVID/XPG4 support if printcap name is set to "lpstat"
* in smb.conf under Solaris.
