1.4004 Thu Mar 10 10:04:28 PST 2011
   [Incompatible Changes]
      - Fixed the issue where `ssh host cpanm Module` waits on input forever. As a side
        effect of fixing this bug, cpanm reads modules from STDIN only if there's no
        module arguments given. Options such as -L or --scandeps continu to work. #86
        (Reported by dku, Getty and many people)

   [Bug Fixes]
      - Fixed a long standing bug where newer versions of bundled modules such as LWP
        could be loaded when combined with -L or -l, which causes API incompatiblities.
      - Fixed the use of gunzip (cho45)

1.4003  Wed Mar  9 18:13:21 PST 2011
      - Fixed a weird bug that -L fails to bootstrap Module::Build when an old version
        such as 0.28 is installed 
      - Do not show help if it reads args from STDIN and nothing is supplied
      - Stripped down the `cpanm` executable size for 20% by stripping POD for fatpacked
        dependencies :)

1.4002  Tue Mar  8 17:47:51 PST 2011
      - Display configure errors in --scandeps so that configure_requires can be
        manually satisfied (suggested by marcus)

1.4001  Tue Mar  8 10:10:28 PST 2011
      - Fixed a workaround code for META.yml being JSON (reported by leedo)

1.4000  Tue Mar  8 01:00:49 PST 2011
   [New Features]
      - Changed the verbosity level of -q to be actually *so* useful and recommended now
      - Added a new option --no-man-pages to skip man page generation and installation
      - Added new --scandeps and --format option that scans module dependency tree before
        actually installing a module
      - Support Bundle:: modules
      - Added new --save-dists option

   See below changes between 1.30_02 and 1.30_13 for more improvements and bug fixes.

1.30_13  Mon Mar  7 10:42:01 PST 2011
   - Fix for the use of Module::CoreList for perl with versions ending in 0, such as 5.13.10.
   - Do not attempt to upgrade Module::Build if you have the version that comes with perl

1.30_12  Sun Mar  6 18:54:41 PST 2011
   - Support Bundle:: modules #81
   - Fixed a bug where META.yml is being fetched for no reason. This reduces the HTTP
     GET calls a lot and should speed up the build process
   - Falls back to search.cpan.org/meta service when (and only when) META.yml is not
     included or unparsable. Now it can handle distributions like AnyEvent::HTTP or
     ancient packages better.
   - Fixed a bug where nmake is doubly quoted on Win32 (charsbar) #76
   - Makes the wget/curl execution safer (J. Nick Koston)
   - Support archives where tar list begins with ./ like Image::Magick (Reported by doy) #80

1.30_11  Sun Mar  6 01:34:59 PST 2011
   - Fix SIGNATURE testing for Module::Build 0.38 or later
   - Implemented EXPERIMENTAL --scandeps command and --format option
   - Implemented EXPERIMENTAL --save-tarballs option
   - Show (undef) in the version output instead of ()

1.30_10  Sat Mar  5 14:55:16 PST 2011
   - Changed how it special cases Module::Build load path in -L mode. It's much more
     reliable and support 0.38 with the new CPAN::Meta dependencies

1.30_09  Fri Mar  4 18:15:40 PST 2011
   - Changed the verbosity level of -q|--quiet so that it prints only necessary
     information (instead of nothing, which is not really useful)
   - Shows the number of distribution in the end of the session

1.30_08  Fri Mar  4 16:04:29 PST 2011
   - Renamed the option to --man-pages and --no-man-pages

1.30_07  Fri Mar  4 15:19:44 PST 2011
   - Disable the man page generation by default only if -L is in use. (suggested by rjbs)

1.30_06  Fri Mar  4 14:55:35 PST 2011
   - Skip the man page generation by default. You can enable it with --pod2man

1.30_05  Fri Mar  4 01:36:28 PST 2011
   - Fixed the way it reduces @INC in the tests when -L is in use, so the tests
     that call $^X with -I can keep those library paths. i.e. Test::More

1.30_04  Fri Mar  4 00:46:24 PST 2011
   - Support minor case where blib/* is manually added via -I (e.g. FCGI.pm)

1.30_03  Fri Mar  4 00:30:39 PST 2011
   - Fixed a bug the modules are not loaded from blib in test_harness with -L

1.30_02  Thu Mar  3 19:53:30 PST 2011
   - Fixed a bug where tests are loading modules from your site_perl even when -L is used

1.3001   Thu Mar  3 18:33:56 PST 2011
   - Documentation overhaul
   - Fixed a bug -L will install non-core modules again and again for each run

1.3000   Wed Mar  2 14:39:44 PST 2011
   - No changes since the last beta

1.29_02  Tue Mar  1 16:06:20 PST 2011
   - Improved the dependencies detection when -L is in use so the core modules that have been upgraded
     inside can be correctly be detected, using Module::CoreList.
   - Added a crazy hack to support Build.PL configure dependencies > 0.36 when -L is in effect

1.29_01  Mon Feb 28 18:57:27 PST 2011
   - Disable --uninstall-shadows by default for perl >= 5.12

1.2001  Wed Feb 16 10:54:21 PST 2011
   - This be official 1.2
   - Skips tests during the bootstrap, making a much better first time experience

1.19_02 Tue Jan 18 14:11:23 PST 2011
   - Module::Metadata now requires version.pm 0.87. This makes cpanm unable to boostrap when version.pm is
     older than that. For now, include the pure perl version/vpp.pm and version.pm in the fatlib and then
     fatpacked in cpanm executable #78

1.19_01 Tue Jan 18 12:48:47 PST 2011
   - Upgraded bundled modules, notably Module::Metadata and local::lib

   - Fixed the usage of local() where PERL5_CPANPLUS_IS_RUNING was leaking (dg) #75

1.1005  Tue Dec 14 15:07:31 PST 2010
   - Accept Foo/Bar/Baz.pm style invocation in args (requested by larryl and many others)

1.1004  Tue Nov 30 10:03:01 PST 2010
   - Fixed a bug where uncompressed and compressed index timestamps are out of sync which causes
     issues when the local and mirror server's clocks are out of sync (reported by sukria)

1.1003  Thu Nov 25 01:17:28 PST 2010
   - Fixed a bug where --mirror-only doesn't detect module version updates (reported by sukria)

   - Implemented --auto-cleanup and set that to 7 (days) by default

1.1001  Fri Nov 12 12:37:31 PST 2010

   - Added --no-wget and --no-curl to bootstrap LWP in an environment with old
     versions of wget/curl (rsp)

1.0012  Fri Aug 20 12:46:34 PDT 2010
   - version check with -L and -l was failing with --skip-installed default. Now fixed (reported by leedo) #55
   - Fixed the code to find root of tarballs (perlpilot)

1.0011  Wed Aug 18 16:38:24 PDT 2010
   - -f now implies --reinstall (perigrin)

1.0010  Fri Jul 30 12:54:03 PDT 2010
   - Make --skip-installed as default
   - Revised documentations

1.0006  Fri Jul  2 16:52:06 PDT 2010

   - Clarified that the minimal perl version supported is 5.8 (chocolateboy)
   - Now being able to look when configure and build fails
   - Automatically disable uninstall_shadows when local::lib is used. This bug was causing
     cpanm to remove modules in @INC with perl 5.10 or older (kazeburo, sugyan)

   - Worked around win32 fork and stdout dup issue (xaicron, charsbar)

1.0002  Sat May  1 20:49:39 PDT 2010
   - Fixed docs
   - Fallback to the version of the distribution filename when META.yml is not parsable

1.0001  Sat Apr 24 16:20:56 CST 2010

      - Deleted --look command
      - Deleted --recent command

   [Improvements]
      - Get metadata from search.cpan.org before fetching tarballs, which makes commands like

      - Added --prompt option that asks users to skip, force install, retry or look when test fails #23

      - Actually changed how -L sets up @INC so that it won't affect the current
