# NOTES: Some of the options are automatic, the rest are enabled/disabled here.
#------------------------------------------------------------------------------
# ?????? HELP appears automatically if the help file exists and is readable.
# INFOCD determines whether users can get information about a CD in drive.
# WIPECD determines whether users can erase a re-writable disk from menu.
# ?????? READ appears if there are any defined read drives.
#          To eliminate READ, undefine CDRx or NAMx for ALL x in 1-9 and a-z.
# LSTIMG determines whether users can list available CD images using menu.
# CHANGE determines whether users can edit CD layout files from menu.
# DELETE determines whether users can delete CD files from menu.
# ?????? WRITE appears if there are any defined write drives.
#          To eliminate WRITE, undefine CDWx or NAMx for ALL x in 1-9 and a-z.
# TESTCD determines whether users can test/verify a CD against an image file.
# CONFIG determines whether users can get into the setup menu from main menu.
# HOTCNF defines extra hotkey for the setup menu; in case it's disabled.
# OTHKEYx defines extra menu commands (up to 15  -- use 1-9 and A-F for x).
# OTHDSCx are the menu descriptions for the 15 extra command keys (With ": ").
# OTHCMDx are the extra commands.  "%k" is for the key pressed, "%." for a "%".
#     You can add plain text between the options using OTHDSCx without OTHKEYx.
#     Commands can begin with QUERY: to ask Yes/No before executing command.
#     Begin with PAUSE: or ERROR: for pausing [always / error] after execution.
#     QUERY: must be first if also using either PAUSE: OR ERROR:.
# QUITSEP is the separator line that prints between the other options and quit.
# QUITDSC is the description for quit command, blanking it will hide option.

# WARNTIME number of minutes of free disk space below which a WARNING occurs.
# IOPTS is added to info commands on all drives.
# EOPTS is added to erase commands for re-writable disks on all drives.
# ROPTS is added to read commands on all drives.
# WOPTS is added to write commands on all drives.
# TOPTS is added to read commands when verifying a disk on all drives.
# NOTES: The read/write options can also be defined by drive selection menu:
#     IOPx is for defining additional (after IOPTS) options for info command.
#     EOPx is for defining additional (after EOPTS) options for erase command.
#     ROPx is for defining additional (after ROPTS) options for read command.
#     WOPx is for defining additional (after WOPTS) options for write command.
#     TOPx is for defining additional (after TOPTS) options when verifying.
#     i.e. Setting "WOP4=xxx" adds xxx after WOPTS value when writing choice 4.
#       YES it WOULD be nice to have options for each drive... in Version 2.
