/* $VERS: bbsExtDL.baud 6.5 (29.10.93)
 copyright 1992 Richard Lee Stockton
         FREELY DISTRIBUTABLE

Allows BBBBS user to download from extra devices like CD drives.
Keeps track of time left to this user, and watches for hangup.

Just ignores file or directory names that contain spaces
 because BBBBS would be unable to download them anyway.

Ignores icons (files that end in .info).

A textfile in BBS:Lists, CD_Exclude, controls exclusion of
 drawers on certain CDs that contain copyright files. Other
 specific files or directories can be excluded by adding
 their paths to the CD_Exclude textfile, one path per line.

Super-sysop may select very large directories and have their
 formatted display lists cached as textfiles in bbspath'Cache'.
 This can greatly improve access time for very large drawers,
 especially if they contain sub-directories.
