changes

source of perl for linux application,

 - When searching for '.modulebuildrc', return the first HOME-like
   directory that actually contains the file instead of the first
   existing directory. Document the search locations and the order
   searched. [Spotted by David Golden]

 - Split the API documentation out of Module::Build::Authoring into
   its own document: Module::Build::API.

 - We should not emit a warning if a Module::Build subclass is
   required in a Makefile.PL that is not bundled in the current
   distribution; it may be installed on the user's system. [Spotted by
   Tyler MacDonald]

 - copy_if_modified() now preserves the executable bit of the source
   file. [Spotted by Julian Mehnle]

 - Fixed compatibility of our screen-scraping the Test::Harness output
   so we can recognize the most recent Test::Harness version. [Steve
   Hay]

 - Backing out a requirement added in 0.27_06 on the method y_n()
   to always include a default. This behavior would cause existing
   build scripts to start failing. We now fail with a missing default
   only when $ENV{PERL_MM_USE_DEFAULT} is set because there is no
   reasonable default.

 - Make install_types() method smarter with respect to custom install
   types.

 - Add documentation for the install_base_relpaths() and
   prefix_relpaths() methods. Improved their usage for a public API,
   and added tests.

0.27_10  Tue Mar 28 22:50:50 CST 2006

 - Added the create_packlist property, default true, which controls
   whether packlist files will be written during installation.  This
   was already part of Module::Build 0.2609, but for some reason we've
   forgotten it in the 0.27_xx series.  [Spotted by Steve Kirkup]

 - Document the versions of Module::Build where each feature, action,
   constructor argument, and method was first publicly documented.

 - More fixes for find_perl_interpreter() to work with BSD flavored
   UNIX: Ensure we always return absolute paths; throw an exception
   upon failure to find correct interperter; document everything.

 - We now include our own YAML.pm work-alike that we can use when the
   real YAML isn't installed.  We might soon even start using it when
   YAML is installed, because the YAML API and dependency chain have
   been changing in unfavorable ways lately. [Stephen Adkins]

 - Fixed some shell-argument-quoting issues on VMS.  In the process,
   we have added some support for avoiding tripping over
   shell-argument-quoting issues on other platforms too. [Initial
   patch by Craig A. Berry]

0.27_09  Sat Mar 11 22:48:54 EST 2006

 - Fixed find_perl_interpreter() so we can find the perl executable
   when running from uninstalled perl even when $^X contains a
   relative path. [Yitzchak Scott-Thoennes]

 - Fixed warning message where we were printing the wrong field names.
   [Chris Dolan]

 - Added a 'testpodcoverage' action that runs a POD coverage check for
   all modules in the distribution. [Yanick Champoux]

 - Added a Cookbook example of subclassing to modify an action. [Dylan
   Martin and David Golden]

 - When building HTML documentation, we were opening the POD file and
   not checking whether the open succeeded, which of course caused
   problems down the line if it failed.  Now we do "or die(...)" like
   everywhere else. [Spotted by Joerg Braun]

0.27_08  Fri Mar  3 21:22:41 CST 2006

 - Due to shell quoting issues and differences in syntax between
   various flavors of Windows, the code for the 'pl2bat' utility
   distributed with Perl has been incorporated into M::B::P::Windows.
   [Thanks to Dr Bean and Ron Savage for help testing and isolating
   the problem.]

 - Modify add_build_element() so that it only adds elements if they
   don't already exist. [David Wheeler]

 - Fixed a bug in the 'pass-through' Makefile.PL in which we would die
   if CPAN::Shell->install returned false, but apparently this return
   value is unreliable.  Now we only die if the module is actually
   unavailable after installation.

 - Fixed testing problems on VMS related to non-case-preserving
   filesystems.  We now bundle Tie::CPHash in the distribution (just
   for testing purposes, it doesn't get installed) to help with
   this. [Craig Berry and Yitzchak Scott-Thoennes]

 - We incorrectly documented the 'dynamic_config' flag in the META.yml
   file as having a default value of false, but according to the
   META.yml spec (which, for heaven's sake, we wrote) its default
   value is true.  Fixed. [Spotted by Adam Kennedy]

 - The have_c_compiler() method was dying if the ExtUtils::CBuilder
   module wasn't around, which is obviously an unhelpful thing to do.
   Now it just returns false. [Spotted by John Peacock]

 - Fix detection of $VERSION expressions that are not
   assignments. [Spotted by Chris Dolan]

 - Obfuscate one of our constructs that uses a $VERSION variable,
   because it was getting picked up by ExtUtils::MakeMaker's
   version-finder. [Spotted by Randal Schwartz]

 - The config_data script for querying and/or setting a module's
   config data was forgetting to call write() after setting config
   values (though setting feature values was working fine).
   Fixed. [Brian Duggan]

 - On Windows, remove the pl2bat generated 'Build.bat' script without
   the annoying "The batch file cannot be found." error.  [Solution
   provided by RazTK and foxidrive on newsgroup alt.msdos.batch]

 - Our version comparisons should now work correctly with modules that
   use version.pm to delcare their versions (e.g. "our $VERSION =
   version->new('1.0.0')"). [John Peacock and Ron Savage]

 - We now create a Build.bat script on versions of Windows where it
   makes sense. [Yves]

 - Fixed the verbiage around choosing the correct make-alike on
   different platforms to suggest using 'perl -V:make'. [Suggested by
   anonymous user]

0.27_07  Wed Feb  1 20:07:45 CST 2006

 - The notes() method now returns the new value when called with two
   arguments, just like when it's called with one argument. [Tyler
   MacDonald]

 - The notes() method now distinguishes among the values undef, 0, and
   the empty string, where previously it didn't. [Tyler MacDonald]

 - We now unshift(@INC) rather than push(@INC) for the directory where
   a build subclass lives, so that we're sure to pick up the right
   version and not some already-installed version. [perlmonkey]

 - The SIGNATURE file for version 0.27_06 (and I'm sure for lots of
   versions before that too!) was messed up, since we were modifying
   some files after signing.  This has been band-aided for the time
   being by signing twice. [Reported by Chris Dolan]

0.27_06  Mon Jan 23 21:44:54 CST 2006

 - Fixed an undefined-variable warning when building the META.yml file
   and the author hasn't used the 'module_name' mechanism. [Chris Dolan]

 - We should now work with recent (> 0.49) versions of YAML.pm when
   creating the META.yml file. [Yitzchak Scott-Thoennes]

 - The y_n() method now requires the default parameter, and the
   prompt() and y_n() methods have been improved with respect to
   how they behave/detect when there is no user to ask.  We're now
   more consistent with MakeMaker, including respecting the
   PERL_MM_USE_DEFAULT environment variable. [Tyler MacDonald and
   Yitzchak Scott-Thoennes]

 - When building a README file using Pod::Text, work around a bug in
   Pod::Text 3.01, which expects Pod::Simple::parse_file to take input
   and output filehandles when it actually only takes an input
   filehandle. [Yitzchak Scott-Thoennes]

0.27_05  Thu Jan 12 17:39:21 CST 2006

 - In t/common.pl, we were attempting to let the user's installed
   Test::More take precedence over ours, but getting thwarted by all
   the test scripts' loading Test::More beforehand.  Fixed. [Spotted
   by Yitzchak Scott-Thoennes]

 - In various test scripts, we were outputting some strings that
   weren't strictly conformant with Test::Harness's expected input,
   though it didn't actually cause problems.  Now we're more
   conformant, though not yet strict. [Spotted by Yitzchak
   Scott-Thoennes]

0.27_04  Fri Dec 23 10:43:34 CST 2005

 - Removed experimental feature that extended the prerequisite system
   to apply ('requires', 'recommends', and 'conflicts') prereqs to all
   actions. Most of the internal extensiblity has been retained so
   that prereq types can easily be added, more selectively.

 - Added a 'prereq_report' action that shows the user a well-formatted
   list of all prerequisites, the versions required, and the versions
   actually installed. [David Wheeler]

 - Clarified the directory name that's created during the 'distdir'
   action. [Suggested by Tyler MacDonald]

 - Fixed a bug when creating the META.yml file without the help of
   YAML.pm - some common strings weren't quoted & escaped properly.
   Now only some uncommon ones are. [Spotted by Joshua ben Jore]

 - Fixed a bug in which an "UNINST=1" argument specified to a
   passthrough Makefile's "make install" wasn't actually seen by
   Module::Build.

 - Rather than dying when the Build script is run from the wrong
   directory, it now simply chdir()s into the right directory and
   keeps going. [Suggested by Dominique Quatravaux]

 - Added an "Examples on CPAN" section to the cookbook, with an
   initial entry pointing to John Peacock's SVN-Notify-Mirror
   distribution.

 - Add an invoked_action() method to return the name of the original
   action invoked by the user.

 - Add 'meta-spec' field to the generated META.yml file, including the
   version of the specification followed by the current Module::Build
   and the url where the specification can be found.

 - Introduced two actions, 'html' & 'manpages', that generate
   documentation for POD when the respective feature is enabled.  The
   actions will generate the documents even if there is no set place
   to install to.  However, if the actions are invoked as a dependency
   of another action (e.g. build), the documentation will only be
   built when there is a default or user-specified place to install to.

 - Added support for environment variable, 'MODULEBUILDRC', which can
   be used to specify the full path to an option file to use instead
   of the default location of ~/.modulebuildrc. A special undocumented
   setting of 'NONE' tells Module::Build not to load any user settings,
   so tests can be run without tainting from user options.

 - Documented and improved preliminary support for more Getopt::Long
   style options are supported, including boolean options (--verbose,
   --no-verbose), and use of hyphens in option names in addition to
   underscores.

 - The option to disable/enable reading of the ~/.modulebuildrc file
   is changed from 'skip_rcfile' to 'use_rcfile'

 - Allow the 'distmeta' action to continue when 'MANIFEST' is missing,
   omitting the generation of the 'provieds' field. [Steven Schubiger]

 - Fixed some failing regex from generated MANIFEST.SKIP file.

 - Fixed an edge case in $VERSION parsing where we thought a package()
   declaration was happening but it wasn't. [David Golden]

 - Added docs for the install_destination() and install_types() methods.

0.27_03 (Beta for 0.28)  Mon Oct 10 11:19:23 EDT 2005

 - We now use ExtUtils::CBuilder to do all compiling of C code (for
   example, when compiling XS modules).  (This change actually
   occurred in 0.27_01, but it was mistakenly omitted from the Changes
   file.)

 - Fixed an issue on Win32 (and other case-tolerant
   non-case-preserving systems, possibly like VMS?) in which the
   current working directory would sometimes be reported with
   different case, fooling us into thinking that we were in the wrong
   directory. [David Golden]

 - The extra_compiler_flags setting was not actually being passed
   along to ExtUtils::CBuilder so it could pass it along to the
   compiler.  Now it is.

 - The synonyms 'scripts' and 'prereq' for 'script_files' and
   'requires' were broken in a previous version (0.27_01, probably),
   but now they're fixed. [David Golden]
 
 - Previously, we assumed that any custom subclass of Module::Build
   was located in _build/lib/.  This is only true if the author used
   the subclass() method, though.  We now use %INC to find where the
   custom subclass really is, so that we can "use lib" it.  We also
   issue a warning if it seems to be outside the build directory.
   [Spotted by Peter Tandler]

 - Added a URL for each license type that we know about, which will
   appear as resources=>license: in the generated META.yml file.

 - If the user passes a no_index parameter to our constructor, we now
   pass that through when building the META.yml file. [Richard
   Soderberg, RT #9603]

 - A few more status messages can now be suppressed by using 'quiet'
   mode.  [Dave Rolsky]

 - Added some more entries to the default MANIFEST.SKIP file. [Chris
   Dolan]

 - Our POD parser will now accept "AUTHORS" as well as "AUTHOR" when
   looking for the author list in a module. [David Wheeler]

 - When looking for the POD to auto-generate a README file, or for the
   AUTHOR or ABSTRACT for the distribution, we now also look for a
   *.pod with the same name as the *.pm file specified by
   'version_from'. [David Golden]

 - The recommended dependency on ExtUtils::ParseXS has been moved into
   the "C_support" auto_feature.

 - When building XS files, we now pass the -DVERSION and -DXS_VERSION
