+# John Simpson <jms1@jms1.net> 2005-04-20
+#
+# reads qmail control files and builds a list of all valid email addresses
+# on the system.
+#
+# 2005-05-04 jms1 - cleaned up the code a little bit. holding the output in
+#   memory until the whole thing is done so that partial output doesn't
+#   become an issue. it also makes it possible to create a cdb file directly,
+#   but i don't think i'm going to do that- i like the "chaining" approach
+#   better, piping this script's output through "cdbmake-12" to produce the
+#   cdb file.
+#
+# 2005-05-09 jms1 - changing the vpopmail user info process. instead of 
+#   reading vpasswd.cdb, using "vuserinfo -D {domain}" and parsing that
+#   output. this should include mysql user information for people who are
+#   using vpopmail with mysql. Thanks to Roman Volf on the qmailrocks
+#   mailing list for pointing this out.
+#
+# 2005-06-09 jms1 - adding support for "fastforward" aliases.
+#
+# 2005-06-18 jms1 - finishing support for .qmail-* files in local user home
+#   directories... i don't ever use local users for mailboxes myself, so it
+#   wasn't an issue for me, but somebody out there may be doing it, so...
+#
+# 2005-06-23 jms1 - changed the search pattern when reading "vuserinfo -D"
+#   to get a vpopmail domain's mailbox list, instead of recognizing \w+
+#   it now uses \S+ which should allow "." in mailbox names
+#
+# 2005-06-29 jms1 - translating ":" to "." in .qmail-* filenames... i forgot
+#   that qmail-local does this. somebody emailed me to remind me about this,
+#   but i can't find the email so i don't know who to thank for reminding me
+#   about this...
+#
+# 2005-06-30 jms1 - when vpopmail stores everything in a mysql database,
+#   aliases are apparently not represented by .qmail files at all. it looks
+#   like we have no choice but to use the vpopmail command-line tools to
+#   get the lists of mailboxes and aliases in the domain. thanks to Rob Pitt
+#   for telling me that this wasn't working (i don't use vpopmail with mysql
+#   so i had no way to know that this would be a problem.)
+#
+# 2005-07-17 jms1 - domains listed in smtproutes are currently listed as
+#   just "@domain", meaning the entire domain is accepted without any checks
+#   done for individual userid's. adding code so that you can create a
+#   directory full of files named for the domains, containing userid's
+#   which exist in that domain. thanks to roman volf for the suggestion.
+#
+# 2005-08-03 jms1 - turns out if vpopmail is compiled with support for mysql,
+#   the "valias -s" command doesn't list aliases which exist by virtue of
+#   .qmail-blah files... which rather sucks, because this is how ezmlm sets
+#   up the aliases it needs, by creating .qmail-blah files. thanks again to
+#   Roman Volf for pointing this out.
+#
+# 2005-10-24 jms1 - adding a "-n" switch to generate a list without the 
+#   system accounts (i.e. no "locals" or "me" domains will be printed.)
+#   note that "fastforward" aliases are considered local, since they are
+#   processed through the local delivery mechanism.
+#
+# 2005-11-29 jms1 - now treats missing vpopmail directory as a warning 
+#   rather than a fatal error.
+#
+# 2005-12-07 jms1 - after reviewing qmail-send.c and controls.c, it 
+#   turns out that the "me" becoming part of "locals" only happens if 
+#   the "control/locals" file does not exist... otherwise an empty 
+#   "control/locals" file means that there are no locals. updating the
+#   script to duplicate this logic.
+#   also replacing ":" with "." in .qmail filenames.
+#   thanks to jeff hedlund for pointing me towards the "me" problem,
+#   and for pointing out my oversight with the ":" thing.
+#
+# 2005-12-29 jms1 - adding an array of numeric uid's (empty by default)
+#   which will be ignored when system uid's are scanned. thanks to
+#   roman volf for the suggestion.
+#
+# 2006-01-08 jms1 - fixed a typo, thanks to "marlowe" for pointing it out.
+#
+# 2006-01-11 jms1 - vpopmail has a "--enable-qmail-ext" option which 
+#   changes how mailbox names are handled. if vpopmail is running WITH
+#   this option, every vpopmail mailbox has an implied "-default" alias
+#   whether there's a .qmail-user-default file there or not. thanks to
+#   robin bowes for pointing this out.
+#
+# 2006-01-12 jms1 - making the script work correctly in the unlikely 
+#   case that the user-ext separator character was changed, either by
+#   changing conf-break before compiling qmail, or specifying a custom
+#   value in the users/cdb file.
+#
+# 2006-02-05 jms1 - adding an "exclude" list, for addresses which you 
+#   may not want to include in the output (i.e. private mailing list
+#   aliases and things like that.) also fixed a bug in the code which
+#   handles the user-ext separator character.
+#
+# 2006-03-26 jms1 - fixed a minor typo in the text of an error message
+#   (which does not affect how the script works.) Thanks to Robin Bowes
+#   for pointing it out.
+#
+# 2006-11-29 jms1 - adding logic to work around the case where users/cdb
+#   just plain doesn't exist (which can happen on systems which don't use
+#   vpopmail etc.) thanks to "Eric d'Alibut" on djb's qmail mailing list
+#   for pointing it out.
