`mev'
=====

   The `mev' program is modeled after `xev'. It prints to `stdout' the
mouse console events it gets.

   `mev''s default behaviour is to get anything, but command line
switches can be used to set the various fields in the `Gpm_Connect'
structure, in order to customize the program's behaviour. I'm using
`mev' to handle mouse events to Emacs.  Note: Emacs Support.

   Command line switches for `mev' are the following:

`-C NUMBER'
     Select a virtual console to get events from.  This is intended to
     be used for debugging.

`-d NUMBER'
     Choose a default mask. By default the server gets any events not
     belonging to the event mask. The mask can be provided either as a
     decimal number, or as a symbolic string.

`-e NUMBER'
     Choose the event mask. By default any event is received. The mask
     can be provided either as a decimal number, or as a symbolic
     string.

`-E'
     Enter emacs mode. In emacs mode events are reported as lisp forms
     rather than numbers. This is the format used by the t-mouse
     package within emacs.

`-f'
     Fit events inside the screen before reporting them. This options
     re-fits drag events, which are allowed to exit the screen border,
     Note: Margins.

`-i'
     Interactive. Accepts input from `stdin' to change connection
     parameters.

`-m NUMBER'
     Choose the minimum modifier mask. Any event with fewer modifiers
     will not be reported to `mev'. It defaults to `0'.  The mask must
     be provided either as a decimal number, or as a symbolic string.

`-M NUMBER'
     Choose the maximum modifier mask. Any event with more modifier
     than specified will not be reported to `mev'.  It defaults to
     `\~0', i.e. all events are received.  The mask must be provided
     either as a decimal number, or as a symbolic string.

`-p'
     Requests to draw the pointer during drags. This option is used by
     emacs to avoid invoking `ioctl()' from lisp code.

   When the arguments are not decimal integers, they are considered
lists of alphanumeric characters, separated by a single non-alphanumeric
character. I use the comma (`,'), but any will do.

   Allowed names for events are `move', `drag', `down' or `press', `up'
or `release', `motion' (which is both `move' and `drag'), and `hard'.

   Allowed names for modifiers are `shift', `leftAlt', `rightAlt',
`anyAlt' (one or the other), `control'.

   When the `-i' switch is specified, `mev' looks at its standard input
as command lines rather than events. The input lines are parsed, and the
commands `push' and `pop' are recognized.

   The `push' command, then, accepts the options `-d', `-e', `-m' and
`-M', with the same meaning described above. Unspecified options retain
the previous value and the resulting masks are used to reopen the
connection with the server. `pop' is used to pop the connection stack.
If an empty stack is popped the program exits.

   Other commands recognized are `info', used to return the stack
depth; `quit' to prematurely terminate the program; and `snapshot' to
get some configuration information from the server.
