+ * Parse printcap file.
+ *
+ * This module does exactly one thing - it looks into the printcap file
+ * and tells callers if a specified string appears as a printer name.
+ *
+ * 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.
+ *
+ * Modified to call CUPS support if printcap name is set to "cups"
+ * in smb.conf.
