/*
* GUMP - Gimp Useless Mail Plugin (or Gump Useless Mail Plugin if
* you prefer) version about .85 I would say... give or take a few
* decimal points
*
*
* by Adrian Likins <adrian@gimp.org>
* 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 *done*
* 9) list of frequently used addreses
* 10) openGL compliance
* 11) better handling of filesave errors
*
*
* As always: The utility of this plugin is left as an exercise for
* the reader
