+isync is a command line application which synchronizes mailboxes; currently
+Maildir and IMAP4 mailboxes are supported. New messages, message deletions
+and flag changes can be propagated both ways. isync is suitable for use in
+IMAP-disconnected mode.
+
+Synchronization is based on unique message identifiers (UIDs), so
+no identification conflicts can occur (as opposed to some other mail
+synchronizers).  Synchronization state is kept in one local text file per
+mailbox pair; multiple replicas of a mailbox can be maintained.
+
+See README.SLACKWARE for setup information after installation.

+	MaildirStore local
+	Path ~/Maildir/
+
+	IMAPAccount My-IMAP-server
+	Host mail.myisp.foo
+	Port 143
+	User myuser
+	#Pass mypass -- if not supplied, mbsync will prompt at runtime
+
+	IMAPStore My-IMAP-store
+	Account My-IMAP-Server
+
+	Channel My-Channel
+	Master :My-IMAP-store:
+	Slave :local:
+	Patterns % !Trash # Synchronize all at this level except Trash
+	Sync All
+	Create Both
+	Expunge Both
+

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
