 The 'sortby' variable describes how the output from the 'prog' command
 is to be ordered. It can have one of 5 values (and their associated
 reverse orders). For each method, the "natural" sort order (or at least,
 what we consider to be the natural order) is the default.

 The reverse sorting orders from those described here are obtained by
 prepending "r" to the 'sortby' value given. (Eg. reverse hostname order
 "hostname" is "rhostname").


 (1) "hostname" 

     Output is sorted on the archive hostname in lexical order.

     Reverse order "rhostname".
   
 (2) "time"

     Output is sorted with the most recent modifcation times of the found
     file/directory names coming first (youngest -> oldest).

     Reverse order "rtime".
 
  (3) "size"

     Output is sorted by the size of the found files/directories, largest
     first.

     Reverse order "rsize".
 
  (4) "filename"

     Sorted in file/directory name lexical order.

     Reverse order "rfilename".
 
  (5) "none"    This is the DEFAULT order.

     Unsorted. There is no reverse order although "rnone" is accepted for
     symmetry.
 

 Typing the keyboard interrupt character ( Ctl-C for most people on UNIX)
 during a search will cause the search to aborted. The results up to that
 time will be sorted (determined by the value of the sortby variable) and
 the results output. This output phase may be aborted by typing the abort
 character a second time.
