scan -- examine or change the scan list

syntax:  scan [-r<string>] [-a<string>] [-z]

ex:      scan
         scan -z
         scan -a /ram
         scan -a *
         scan -a .61
         scan -a .62utils
         scan -r /hard2/sys/

With no options, prints the list of directories Davex scans when
you type something that isn't an internal command.

Use the -a and -r options to add or remove a paths from the list.

The special path '*' in the scan list tells Davex to scan the
directory your prefix is set to.

Use 'scan -z' to reset the scan list to the default (the default
is "%" followed by "*").

Note:  If '%' and '.##' shorthand forms are used in the scan
list, they are expanded during scanning, not when they are entered
into the list.  This lets you specify that Davex should scan
certain _drives_ (or directories on whatever volumes are found in
them) rather than certain volumes.
