mewl [options] [folder [range]]

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

The options are as follows:

-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.

-m options

Specify options for command.

-f fields

Specify fields to display.

-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>'

If a field is long, only the beginning three lines are extracted by default.
