Overview

simple singleton module. far less complete and insane than the ruby standard library one, but it automatically forwards methods calls and allows for constructors that take arguments.

classes that inherit this can define initialize. however, you cannot call .new on the class. To get the instance of the class, call .instance; to create the instance, call init.

a source error is either a FatalSourceError or an OutOfSyncSourceError. the superclass SourceError is just a generic.

Source error notification
-------------------------

Hi there. It looks like one or more message sources is reporting
errors. Until this is corrected, messages from these sources cannot
be viewed, and new messages will not be detected.

Out-of-sync source notification
-------------------------------

Hi there. It looks like one or more sources has fallen out of sync
with my index. This can happen when you modify these sources with
other email clients. (Sorry, I don't play well with others.)

Until this is corrected, messages from these sources cannot be viewed,
and new messages will not be detected. Luckily, this is easy to correct!

"Source: " + s.to_s +
 "\n Error: " + s.error.message.wrap(70).join("\n        ") +

WARNING
-------

#{details}

It is *strongly* recommended that you run "sup-sync-back-maildir"
before continuing, otherwise you might lose changes you have made in sup
to your Xapian index.

This script should be run each time you change the
"sync_back_to_maildir" flag in config.yaml from false to true or
the "sync_back" flag is changed to true for a source in sources.yaml.

Please run "sup-sync-back-maildir -h" for more information and why this
is needed.

Note that if you have any sources that are not marked as 'ususal' in
sources.yaml you need to manually specify them when running  the
sup-sync-back-maildir script.

Are you really sure you want to continue? (y/N)
