to print a generated PostScript file. When lpd(8) is used, lpr(1) from base
must be used. Also, status command for lpc(8) requires a printer name. If
no argument is specified, i.e., "/usr/sbin/lpc status", then it displays the
command usage, i.e., "usage: status {all | printer ...}". Unfortunately,
"usage" is interpreted as a printer name because ":" is included. Add "all"
and adjust an expression for grep(1).
able to find libjli.so from RPATH because argv[0] points to the symlink.
Note it seems Linux does not have the problem when /proc/self/exe exists.
If it does not exist, it also fails to find libjli.so. Clean up patches
while I am here.
