-=head1 NAME
-
-ae2cvs - convert an Aegis change set to CVS commands
-
-=head1 SYNOPSIS
-
-ae2cvs [-aedist|-aegis] [-c change] [-d cvs_root] [-f file] [-l lib]
-	[-m module] [-n] [-p proj] [-q] [-u dir] [-v] [-x] [-X]
-
-	-aedist		use aedist format from input (default)
-	-aegis		query aegis repository directly
-	-c change	change number
-	-d cvs_root	CVS root directory
-	-f file		read aedist from file ('-' == stdin)
-	-l lib		Aegis library directory
-	-m module	CVS module
-	-n		no execute
-	-p proj		project name
-	-q		quiet, don't print commands
-	-u dir		use dir for CVS checkin
-	-v		print version string and exit
-	-x		execute the commands, but don't commit;
-			two or more -x options commit changes
-	-X		execute the commands and commit changes
-
-=head1 DESCRIPTION
-
-The C<ae2cvs> utility can convert an Aegis change into a set of CVS (and
-other) commands to make the corresponding change(s) to a carbon-copy CVS
-repository.  This can be used to keep a front-end CVS repository in sync
-with changes made to an Aegis project, either manually or automatically
-using the C<integrate_pass_notify_command> attribute of the Aegis
-project.
-
-By default, C<ae2cvs> makes no changes to any software, and only prints
-out the necessary commands.  These commands can be examined first for
-safety, and then fed to any Bourne shell variant (sh, ksh, or bash) to
-make the actual CVS changes.
-
-An option exists to have C<ae2cvs> execute the commands directly.
-
-=head1 OPTIONS
-
-The C<ae2cvs> utility supports the following options:
-
-=over 4
-
-=item -aedist
-
-Reads an aedist change set.
-By default, the change set is read from standard input,
-or a file specified with the C<-f> option.
-
-=item -aegis
-
-Reads the change directly from the Aegis repository
-by executing the proper C<aegis> commands.
-
-=item -c change
-
-Specify the Aegis change number to be used.
-The value of the C<AEGIS_CHANGE> environment variable
-is used by default.
-
-=item -d cvsroot
-
-Specify the CVS root directory to be used.
-This option is passed explicitly to each executed C<cvs> command.
-The default behavior is to omit any C<-d> options
-and let the executed C<cvs> commands use the
-C<CVSROOT> environment variable as they normally would.
-
-=item -f file
-
-Reads the aedist change set from the specified C<file>,
-or from standard input if C<file> is C<'-'>.
-
-=item -l lib
-
-Specifies an Aegis library directory to be searched for global states
-files and user state files.
-
-=item -m module
-
-Specifies the name of the CVS module to be brought up-to-date.
-The default is to use the Aegis project name,
-minus any branch numbers;
-for example, given an Aegis project name of C<foo-cmd.0.1>,
-the default CVS module name is C<foo-cmd>.
-
-=item -n
-
-No execute.  Commands are printed (including a command for a final
-commit of changes), but not executed.  This is the default.
-
-=item -p proj
-
-Specifies the name of the Aegis project from which this change is taken.
-The value of the C<AEGIS_PROJECT> environment variable
-is used by default.
-
-=item -q
-
-Quiet.  Commands are not printed.
-
-=item -u dir
-
-Use the already checked-out CVS tree that exists at C<dir>
-for the checkins and commits.
-The default is to use a separately-created temporary directory.
-
-=item -v
-
-Print the version string and exit.
-
-=item -x
-
-Execute the commands to bring the CVS repository up to date,
-except for the final commit of the changes.  Two or more
-C<-x> options will cause the change to be committed.
-
-=item -X
-
-Execute the commands to bring the CVS repository up to date,
-including the final commit of the changes.
-
-=back
-
-=head1 ENVIRONMENT VARIABLES
-
-=over 4
-
-=item AE2CVS_FLAGS
-
-Specifies any options to be used to initialize
-the C<ae2cvs> utility.
-Options on the command line override these values.
-
-=back
-
-=head1 AUTHOR
-
-Steven Knight (knight at baldmt dot com)
-
-=head1 BUGS
-
-If errors occur during the execution of the Aegis or CVS commands, and
-the -X option is used, a partial change (consisting of those files for
-which the command(s) succeeded) will be committed.  It would be safer to
-generate code to detect the error and print a warning.
-
-When a file has been deleted in Aegis, the standard whiteout file can
-cause a regex failure in this script.  It doesn't necessarily happen all
-the time, though, so this needs more investigation.
-
-=head1 TODO
-
-Add an explicit test for using ae2cvs in the Aegis
-integrate_pass_notify_command field to support fully keeping a
-repository in sync automatically.

-  XXX The primary purpose of this release ... XXX
-
-  A SCons "checkpoint release" is intended to provide early access to
-  new features so they can be tested in the field before being released
-  for adoption by other software distributions.
-
-  Note that a checkpoint release is developed using the same test-driven
-  development methodology as all SCons releases.  Existing SCons
-  functionality should all work as it does in previous releases (except
-  for any changes identified in the release notes) and early adopters
-  should be able to use a checkpoint release safely for production work
-  with existing SConscript files.  If not, it represents not only a bug
-  in SCons but also a hole in the regression test suite, and we want to
-  hear about it.
-
-  New features may be more lightly tested than in past releases,
-  especially as concerns their interaction with all of the other
-  functionality in SCons.  We are especially interested in hearing bug
-  reports about new functionality.
-
-  We do not recommend that downstream distributions (Debian, Fedora,
-  etc.) package a checkpoint release, mainly to avoid confusing the
-  "public" release numbering with the long checkpoint release names.
-
-  Here is a summary of the changes since 1.3.0:

   NEW FUNCTIONALITY
 
-    - List new features (presumably why a checkpoint is being released)
+    - None
 
   DEPRECATED FUNCTIONALITY
 
-    - List anything that's been deprecated since the last release
+    - None
 
   CHANGED/ENHANCED EXISTING FUNCTIONALITY
 
-    - List modifications to existing features, where the previous behavior
-      wouldn't actually be considered a bug
+    - None
 
   FIXES
 
-    - List fixes of outright bugs
+    - None
 
   IMPROVEMENTS
 
-    - List improvements that wouldn't be visible to the user in the
-      documentation:  performance improvements (describe the circumstances
-      under which they would be observed), or major code cleanups
+    - Switched several core classes to use "slots", to

+      projects (fixes #2180, #2178, #2198)
+    - Memoizer counting uses decorators now, instead of

   PACKAGING
 
-    - List changes in the way SCons is packaged and/or released

   DOCUMENTATION

-Historical Note:  The initial Memoizer implementation actually handled

-algorithms for computing hashable values based on the method's arguments.
-This collected caching logic nicely, but had two drawbacks:
-
-    Running arguments through a generic key-conversion mechanism is slower
-    (and less flexible) than just coding these things directly.  Since the

-    slowing them down in order to collect the logic isn't the right

-    Use of the memoizer really obscured what was being called, because
-    all the memoized methods were wrapped with re-used generic methods.
