.ie n .Sh "$bool\fP = \f(CW$dist\fP\->\fIformat_available();"
.el .Sh "\f(CW$bool\fP = \f(CW$dist\fP\->\fIformat_available()\fP;"
.IX Subsection "$bool = $dist->format_available();"
Returns a boolean indicating whether or not you can use this package
to create and install modules in your environment.
.PP
Sets up the \f(CW\*(C`CPANPLUS::Dist::MM\*(C'\fR object for use. 
Effectively creates all the needed status accessors.
.PP
Called automatically whenever you create a new \f(CW\*(C`CPANPLUS::Dist\*(C'\fR object.
.PP
\&\f(CW\*(C`prepare\*(C'\fR preps a distribution for installation. This means it will 
run \f(CW\*(C`perl Makefile.PL\*(C'\fR and determine what prerequisites this distribution
declared.
.PP
If you set \f(CW\*(C`force\*(C'\fR to true, it will go over all the stages of the 
\&\f(CW\*(C`prepare\*(C'\fR process again, ignoring any previously cached results.
.PP
When running \f(CW\*(C`perl Makefile.PL\*(C'\fR, the environment variable
\&\f(CW\*(C`PERL5_CPANPLUS_IS_EXECUTING\*(C'\fR will be set to the full path of the
\&\f(CW\*(C`Makefile.PL\*(C'\fR that is being executed. This enables any code inside
the \f(CW\*(C`Makefile.PL\*(C'\fR to know that it is being installed via \s-1CPANPLUS\s0.
.PP
Returns true on success and false on failure.
.PP
You may then call \f(CW\*(C`$dist\->create\*(C'\fR on the object to create the
installable files.
.ie n .Sh "$href\fP = \f(CW$dist\->_find_prereqs( file => '/path/to/Makefile', [verbose => \s-1BOOL\s0])"
.el .Sh "\f(CW$href\fP = \f(CW$dist\fP\->_find_prereqs( file => '/path/to/Makefile', [verbose => \s-1BOOL\s0])"
.IX Subsection "$href = $dist->_find_prereqs( file => '/path/to/Makefile', [verbose => BOOL])"
Parses a \f(CW\*(C`Makefile\*(C'\fR for \f(CW\*(C`PREREQ_PM\*(C'\fR entries and distills from that
any prerequisites mentioned in the \f(CW\*(C`Makefile\*(C'\fR
.PP
Returns a hash with module-version pairs on success and false on
failure.
.ie n .Sh "$bool\fP = \f(CW$dist\->create([perl => '/path/to/perl', make => '/path/to/make', makeflags => 'EXTRA=FLAGS', prereq_target => \s-1TARGET\s0, skiptest => \s-1BOOL\s0, force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.el .Sh "\f(CW$bool\fP = \f(CW$dist\fP\->create([perl => '/path/to/perl', make => '/path/to/make', makeflags => 'EXTRA=FLAGS', prereq_target => \s-1TARGET\s0, skiptest => \s-1BOOL\s0, force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.IX Subsection "$bool = $dist->create([perl => '/path/to/perl', make => '/path/to/make', makeflags => 'EXTRA=FLAGS', prereq_target => TARGET, skiptest => BOOL, force => BOOL, verbose => BOOL])"
\&\f(CW\*(C`create\*(C'\fR creates the files necessary for installation. This means 
it will run \f(CW\*(C`make\*(C'\fR and \f(CW\*(C`make test\*(C'\fR.  This will also scan for and 
attempt to satisfy any prerequisites the module may have.
.PP
If you set \f(CW\*(C`skiptest\*(C'\fR to true, it will skip the \f(CW\*(C`make test\*(C'\fR stage.
If you set \f(CW\*(C`force\*(C'\fR to true, it will go over all the stages of the 
\&\f(CW\*(C`make\*(C'\fR process again, ignoring any previously cached results. It 
will also ignore a bad return value from \f(CW\*(C`make test\*(C'\fR and still allow 
the operation to return true.
.PP
Returns true on success and false on failure.
.PP
You may then call \f(CW\*(C`$dist\->install\*(C'\fR on the object to actually
install it.
.ie n .Sh "$bool\fP = \f(CW$dist\->install([make => '/path/to/make',  makemakerflags => 'EXTRA=FLAGS', force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.el .Sh "\f(CW$bool\fP = \f(CW$dist\fP\->install([make => '/path/to/make',  makemakerflags => 'EXTRA=FLAGS', force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.IX Subsection "$bool = $dist->install([make => '/path/to/make',  makemakerflags => 'EXTRA=FLAGS', force => BOOL, verbose => BOOL])"
\&\f(CW\*(C`install\*(C'\fR runs the following command:
    make install
.PP
Returns true on success, false on failure.
.ie n .Sh "$bool\fP = \f(CW$dist\->write_makefile_pl([force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.el .Sh "\f(CW$bool\fP = \f(CW$dist\fP\->write_makefile_pl([force => \s-1BOOL\s0, verbose => \s-1BOOL\s0])"
.IX Subsection "$bool = $dist->write_makefile_pl([force => BOOL, verbose => BOOL])"
This routine can write a \f(CW\*(C`Makefile.PL\*(C'\fR from the information in a 
module object. It is used to write a \f(CW\*(C`Makefile.PL\*(C'\fR when the original
author forgot it (!!).
.PP
Returns 1 on success and false on failure.
.PP
The file gets written to the directory the module's been extracted 
to.
