       mewl [options] [folder [range]]


       The  mewl  utility  extracts  necessary  fields from messages stored in
       folders.   This  command  is  necessary  for  Mew  to   implement   the

       -a      Print all necessary fields when picking.

       -b dir  Set the Mail home to dir.

       -c bodylen
               Set the max body length to be extracted to bodylen.

       -d field
               Set the field to be extracted to field.

       -e command
               Specify an external command to fetch mailbox.

       -h      Display this help message.

       -i file Set the input stream to file.

       -l length
               Set  the  max  field  length  to  be  extracted to length.  The
               default value is 3. 0 means no limit.

       -n      Don’t use fstat().

       -p pattern
               Specify the pick pattern.

       -s src  Set message source to src : ’+folder range’.

       -w      Wait for stdio input to synchronize.

       -v      Display the version.

       -x suffix
               Use this suffix.

               Definitions of the symbols above are as follows:

       range   N | [start]-[end] | last:N

       pattern ´key=val’  |  ’key!=val’  |  ’!<pattern>’  |  ’(<pattern>)’   |
               ’<pattern>&<pattern>’ | ’<pattern>|<pattern>’
