55 C<CPANPLUS::Dist::Build> is a distribution class for C<Module::Build>
57 Using this package, you can create, install and uninstall perl
58 modules. It inherits from C<CPANPLUS::Dist>.
60 Normal users won't have to worry about the interface to this module,
61 as it functions transparently as a plug-in to C<CPANPLUS> and will
62 just C<Do The Right Thing> when it's loaded.
70 Returns the C<CPANPLUS::Module> object that parented this object.
74 Returns the C<Object::Accessor> object that keeps the status for
79 =head1 STATUS ACCESSORS
81 All accessors can be accessed as follows:
82 $build->status->ACCESSOR
88 Location of the Build file.
89 Set to 0 explicitly if something went wrong.
93 BOOL indicating if the C<Build> command was successful.
97 BOOL indicating if the C<Build test> command was successful.
101 BOOL indicating if the C<prepare> call exited succesfully
102 This gets set after C<perl Build.PL>
106 Full path to the directory in which the C<prepare> call took place,
107 set after a call to C<prepare>.
111 BOOL indicating if the C<create> call exited succesfully. This gets
112 set after C<Build> and C<Build test>.
114 =item C<installed ()>
116 BOOL indicating if the module was installed. This gets set after
117 C<Build install> exits successfully.
121 BOOL indicating if the module was uninstalled properly.
123 =item C<_create_args ()>
125 Storage of the arguments passed to C<create> for this object. Used
126 for recursive calls when satisfying prerequisites.
128 =item C<_install_args ()>
130 Storage of the arguments passed to C<install> for this object. Used
131 for recursive calls when satisfying prerequisites.
139 =head2 $bool = CPANPLUS::Dist::Build->format_available();
141 Returns a boolean indicating whether or not you can use this package
142 to create and install modules in your environment.

161 Sets up the C<CPANPLUS::Dist::Build> object for use.

187 C<prepare> prepares a distribution, running C<Build.PL>
188 and establishing any prerequisites this
191 The variable C<PERL5_CPANPLUS_IS_EXECUTING> will be set to the full path
192 of the C<Build.PL> that is being executed. This enables any code inside
193 the C<Build.PL> to know that it is being installed via CPANPLUS.
