4$!    Possible command line arguments include
5$!	"-uConan-B"	!play a barbarian named Conan
6$!	"-u" "Merlin-W" !play a wizard named Merlin (slight variant of above)
7$!	"-e" or "-E"	!play an elf with default name (from environment
8$!			! [ie, NETHACKOPTIONS logical name] or VMS username)
9$!	"-a" or "-A", "-b" or "-B", "-c" or "-C", ... !specify character type
10$!			!note: "-s" is ambiguous between "play as a samurai"
11$!			!   vs "show scoreboard", so use "-S" for the former
12$!	"-x" or "-X"	!play in 'explore' mode (practice for beginners)
13$!	"-D"		!play in 'wizard' mode (for debugging, available only
14$!			! to the username compiled into nethack.exe as WIZARD)
15$!	"-dec"		!turn on DECgraphics mode (VT100 line drawing, done
16$!			! automatically below if appropriate term attribs set)
17$!	"-d" dir-path	!specify an alternate playground directory (not
18$!			! recommended; define HACKDIR instead)
