-# "Simple but Perfect" mbox to Maildir converter v0.1
-# by Philip Mak <pmak@aaanime.net>
-
-# Usage: perfect_maildir ~/Maildir < mbox
-
-# Simple - only converts one mbox (can use script in one-liners)
-# Perfect - message Flags/X-Flags are converted; "^>From ." line is unescaped
-
-# I wrote this script after being unsatisfied with existing mbox to
-# maildir converters. By making it "Simple", code complexity is kept
-# low thus making it easy to program and debug. At the same time,
-# since it only converts one mbox at a time, it is perfect for use in
-# a shell `for'' loop (for example).
-
-# As for being "Perfect", to the best of my knowledge this script does
-# the conversion correctly in all cases; it will translate "Status"
-# and "X-Status" fields into maildir info, and it correctly detects
-# where messages begin and end. (This is only version 0.1 so I may
-# have messed something up though. Please send me feedback!)
-
-# NOTE: The MUA `mutt'' has a bug/feature where in the message index,
-# it claims that all maildir messages have 0 lines unless they have a
-# "Lines:" header set. perfect_maildir does not attempt to add the
-# "Lines:" header; you may want to reconfigure `mutt' to display byte
-# size instead of lines instead by adding the following line to your
-# ~/.muttrc file:
-#
-# set index_format="%4C %Z %{%b %d} %-15.15L (%4c) %s"
