 Examine whether module loading is delayed until actual referring, even
 though module is imported with "absolute_import" feature.
 
 Files below in each packages are used for described purpose:
 
 - "called": examine whether "from MODULE import ATTR" works correctly
 - "unused": examine whether loading is delayed correctly
 - "used":   examine whether "from PACKAGE import MODULE" works correctly
 
 Package hierarchy is needed to examine whether demand importing works
 as expected for "from SUB.PACK.AGE import MODULE".

   (use 'hg help extensions' for information on enabling extensions)

   $ hg help extdiff
   hg extdiff [OPT]... [FILE]...
   
   use external program to diff repository (or selected files)
   
       Show differences between revisions for the specified files, using an
       external program. The default program used is diff, with default options
       "-Npru".
   
       To select a different program, use the -p/--program option. The program
       will be passed the names of two directories to compare. To pass additional
       options to the program, use -o/--option. These will be passed before the
       names of the directories to compare.
   
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision is
       compared to the working directory, and, when no revisions are specified,
       the working directory files are compared to its parent.

   $ hg help --extension extdiff
   extdiff extension - command to allow external programs to compare revisions
   
   The extdiff Mercurial extension allows you to use external programs to compare
   revisions, or revision with working directory. The external diff programs are
   called with a configurable set of options and two non-option arguments: paths
   to directories containing snapshots of files to compare.
   
   If there is more than one file being compared and the "child" revision is the
   working directory, any modifications made in the external diff program will be
   copied back to the working directory from the temporary directory.
   
   The extdiff extension also allows you to configure new diff commands, so you
   do not need to type 'hg extdiff -p kdiff3' always.
   
     [extdiff]
     # add new command that runs GNU diff(1) in 'context diff' mode
     cdiff = gdiff -Nprc5
     ## or the old way:
     #cmd.cdiff = gdiff
     #opts.cdiff = -Nprc5
   
     # add new command called meld, runs meld (no need to name twice).  If
     # the meld executable is not available, the meld tool in [merge-tools]
     # will be used, if available
     meld =
   
     # add new command called vimdiff, runs gvimdiff with DirDiff plugin
     # (see http://www.vim.org/scripts/script.php?script_id=102) Non
     # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
     # your .vimrc
     vimdiff = gvim -f "+next" \
               "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
   
   Tool arguments can include variables that are expanded at runtime:
   
     $parent1, $plabel1 - filename, descriptive label of first parent
     $child,   $clabel  - filename, descriptive label of child revision
     $parent2, $plabel2 - filename, descriptive label of second parent
     $root              - repository root
     $parent is an alias for $parent1.
   
   The extdiff extension will look in your [diff-tools] and [merge-tools]
   sections for diff tool arguments, when none are specified in [extdiff].
   
     [extdiff]
     kdiff3 =
   
     [diff-tools]
     kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
   
   You can use -I/-X and list of file or directory names like normal 'hg diff'
   command. The extdiff extension makes snapshots of only needed files, so
   running the external diff program will actually be pretty fast (at least
   faster than having to compare the entire tree).
   
   list of commands:
   
    extdiff       use external program to diff repository (or selected files)
   
   (use 'hg help -v -e extdiff' to show built-in aliases and global options)

 Disabled extension commands:
 
   $ ORGHGRCPATH=$HGRCPATH
   $ HGRCPATH=
   $ export HGRCPATH
   $ hg help email
   'email' is provided by the following extension:
   
       patchbomb     command to send changesets as (a series of) patch emails
   
   (use 'hg help extensions' for information on enabling extensions)
 
 
   $ hg qdel
   hg: unknown command 'qdel'
   'qdelete' is provided by the following extension:
   
       mq            manage a stack of patches
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
   $ hg churn
   hg: unknown command 'churn'
   'churn' is provided by the following extension:
   
       churn         command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
   [255]
 
 
 
 Disabled extensions:
 
   $ hg help churn
   churn extension - command to display statistics about repository history
   
   (use 'hg help extensions' for information on enabling extensions)
 
   $ hg help patchbomb
   patchbomb extension - command to send changesets as (a series of) patch emails
   
   The series is started off with a "[PATCH 0 of N]" introduction, which
   describes the series as a whole.
   
   Each patch email has a Subject line of "[PATCH M of N] ...", using the first
   line of the changeset description as the subject text. The message contains
   two or three body parts:
   
   - The changeset description.
   - [Optional] The result of running diffstat on the patch.
   - The patch itself, as generated by 'hg export'.
   
   Each message refers to the first in the series using the In-Reply-To and
   References headers, so they will show up as a sequence in threaded mail and
   news readers, and in mail archives.
   
   To configure other defaults, add a section like this to your configuration
   file:
   
     [email]
     from = My Name <my@email>
     to = recipient1, recipient2, ...
     cc = cc1, cc2, ...
     bcc = bcc1, bcc2, ...
     reply-to = address1, address2, ...
   
   Use "[patchbomb]" as configuration section name if you need to override global
   "[email]" address settings.
   
   Then you can use the 'hg email' command to mail a series of changesets as a
   patchbomb.
   
   You can also either configure the method option in the email section to be a
   sendmail compatible mailer or fill out the [smtp] section so that the
   patchbomb extension can automatically send patchbombs directly from the
   commandline. See the [email] and [smtp] sections in hgrc(5) for details.
   
   By default, 'hg email' will prompt for a "To" or "CC" header if you do not
   supply one via configuration or the command line.  You can override this to
   never prompt by configuring an empty value:
   
     [email]
     cc =
   
   You can control the default inclusion of an introduction message with the
   "patchbomb.intro" configuration option. The configuration is always
   overwritten by command line flags like --intro and --desc:
   
     [patchbomb]
     intro=auto   # include introduction message if more than 1 patch (default)
     intro=never  # never include an introduction message
     intro=always # always include an introduction message
   
   You can specify a template for flags to be added in subject prefixes. Flags
   specified by --flag option are exported as "{flags}" keyword:
   
     [patchbomb]
     flagtemplate = "{separate(' ',
                               ifeq(branch, 'default', '', branch|upper),
                               flags)}"
   
   You can set patchbomb to always ask for confirmation by setting
   "patchbomb.confirm" to true.
