+# This defines a bash command named `edit' which contacts/resumes an
+# existing emacs or starts a new one if none exists.
+#
+# One way or another, any arguments are passed to emacs to specify files
+# (provided you have loaded `resume.el').
+#
+# This function assumes the emacs program is named `emacs' and is somewhere
+# in your load path.  If either of these is not true, the most portable
+# (and convenient) thing to do is to make an alias called emacs which
+# refers to the real program, e.g. 
+#
+#        alias emacs=/usr/local/bin/gemacs
+#
