+#!/bin/bash
+#
+# Author: Eric Gebhart
+#
+# Purpose: To be called by mutt as indicated by .mailcap to handle mail attachments.
+#
+# Function: Copy the given file to a temporary directory so mutt
+# Won't delete it before it is read by the application.
+#
+# Along the way, discern the file type or use the type
+# That is given.
+#
+# Finally use 'open' or 'open -a' if the third argument is
+# given.
+#
+#
+# Arguments:
+#
+# $1 is the file
+# $2 is the type - for those times when file magic isn't enough.
+# I frequently get html mail that has no extension
+# and file can't figure out what it is.
+#
+# Set to '-' if you don't want the type to be discerned.
+# Many applications can sniff out the type on their own.
+# And they do a better job of it too.
+#
+# Open Office and MS Office for example.
+#
+# $3 is open with. as in open -a 'open with this .app' foo.xls
+#
+# Examples: These are typical .mailcap entries which use this program.
+#
+# Image/JPEG; /usr/local/bin/view_attachment %s
+# Image/PNG; /usr/local/bin/view_attachment %s
+# Image/GIF; /usr/local/bin/view_attachment %s
+#
+# Application/PDF; /usr/local/bin/view_attachment %s
+#
+# #This HTML example passes the type because file doesn't always work and
+# #there aren't always extensions.
+#
+# text/html; /usr/local/bin/view_attachment %s html
+#
+# # If your Start OpenOffice.org.app is spelled with a space like this one, <--
+# # then you'll need to precede the space with a \ . I found that too painful
+# # and renamed it with an _.
+#
+# Application/vnd.ms-excel; /usr/local/bin/view_attachment %s "-" '/Applications/OpenOffice.org1.1.2/Start_OpenOffice.org.app'

+# Debugging: If you have problems set debug to 'yes'. That will cause a debug file
+# be written to /tmp/mutt_attach/debug so you can see what is going on.
