/*
* GUMP - Gimp Useless Mail Plugin (or Gump Useless Mail Plugin if you prefer)
* version about .80 I would say... give or take a few decimal points
*
*
* by Adrian Likins <aklikins@eos.ncsu.edu>
* MIME encapsulation by Reagan Blundell <reagan@emails.net>
*
*
*
* Based heavily on gz.c by Daniel Risacher
*
* Lets you choose to send a image to the mail from the file save as dialog.
* images are piped to uuencode and then to mail...
*
*
* This works fine for .99.10. I havent actually tried it in combination with
* the gz plugin, but it works with all other file types. I will eventually get
* around to making sure it works with gz.
*
* To use: 1) image->File->mail image
* 2) when the mail dialog popups up, fill it out. Only to: and filename are required
* note: the filename needs to a type that the image can be saved as. otherwise
* you will just send an empty message.
* 3) click ok and it should be on its way
*
*
* NOTE: You probabaly need sendmail installed. If your sendmail is in an odd spot
* you can change the #define below. If you use qmail or other MTA's, and this
* works after changing the MAILER, let me know how well or what changes were
* needed.
*
* NOTE: Uuencode is needed. If it is in the path, it should work fine as is. Other-
* wise just change the UUENCODE.
*
*
* TODO: 1) the aforementioned abilty to specify the
* uuencode filename *done*
* 2) someway to do this without tmp files
* * wont happen anytime soon*
* 3) MIME? *done*
* 4) a pointlessly snazzier dialog
* 5) make sure it works with gz
* * works for .xcfgz but not .xcf.gz *
* 6) add an option to choose if mail get
* uuencode or not (or MIME'ed for that matter)
* 7) realtime preview
* 8) better entry for comments
* 9) list of frequently used addreses
* 10) openGL compliance
* 11) better handling of filesave errors
*
*
* Version history
* .5 - 6/30/97 - inital relese
* .51 - 7/3/97 - fixed a few spelling errors and the like
* .65 - 7/4/97 - a fairly significant revision. changed it from a file
* plugin to an image plugin.
* - Changed some strcats into strcpy to be a bit more robust.
* - added the abilty to specify the filename you want it sent as
* - no more annoying hassles with the file saves as dialog
* - plugin now registers itself as <image>/File/Mail image
* .7 - 9/12/97 - (RB) added support for MIME encapsulation
* .71 - 9/17/97 - (RB) included Base64 encoding functions from mpack
* instead of using external program.
* - General cleanup of the MIME handling code.
* .80 - 6/23/98 - Added a text box so you can compose real messages.
*
* As always: The utility of this plugin is left as an exercise for the reader
*
