NAME
     gather - gather up the files in a directory for transmission

SYNOPSIS
     gather [-s] source_dir [-d] dest_dir [-b] bytes [-f] file

OPTIONS

     -b   Desired number of bytes per output file

     -d   Destination directory

     -f   Base name of output files

     -s   Source directory

EXAMPLES

     gather              # Collect files in current dir into 60K archives

     gather -d dir       # Put the archives in dir

     gather -b 90000     # Try to produce 90K archives

     gather -s .. -d targ -b 5000
                         # Try to produce 5K archives

DESCRIPTION

     It is often useful to collect all the files in a directory  into  one  or
     more  archives  for  transmission by mail.  This program collects all the
     files in the source directory (default: current directory) and puts  them
     into  a shar archive.  The shar archive is then compressed and uuencoded.
     An attempt is made to have the final .uue file be about  the  given  size
     (default: 60K), but since gather cannot really predict how much shar will
     add to the file, how much compress will reduce the file, and how much uue
     will  add  again, the sizes can fluctuate.  If the -f file flag is given,
     the archives will be given the names file_00.uue, file_01.uue etc.  If -f
     is  not given, the name of the source directory is used as the base name.
     Since 7 characters of suffix are  appended,  the  base  name  should  not
     exceed 7 characters.
