This module is the guts of \s-1CPANPLUS\s0 \*(-- it inherits from all other
modules in the CPANPLUS::Internals::* namespace, thus defying normal
rules of \s-1OO\s0 programming \*(-- but if you're reading this, you already
know what's going on ;)

Please read the \f(CW\*(C`CPANPLUS::Backend\*(C'\fR documentation for the normal \s-1API\s0.

.IX Subsection "$internals = CPANPLUS::Internals->_init( _conf => CONFIG_OBJ )"
\&\f(CW\*(C`_init\*(C'\fR creates a new CPANPLUS::Internals object.
.PP
You have to pass it a valid \f(CW\*(C`CPANPLUS::Configure\*(C'\fR object.
.PP
Returns the object on success, or dies on failure.
.ie n .Sh "$bool\fP = \f(CW$internals\->_flush( list => \e@caches )"
.el .Sh "\f(CW$bool\fP = \f(CW$internals\fP\->_flush( list => \e@caches )"
.IX Subsection "$bool = $internals->_flush( list => @caches )"
Flushes the designated caches from the \f(CW\*(C`CPANPLUS\*(C'\fR object.
.PP
Returns true on success, false if one or more caches could not be
be flushed.
.ie n .Sh "$bool\fP = \f(CW$internals\->_register_callback( name => \s-1CALLBACK_NAME\s0, code => \s-1CODEREF\s0 );"

.IX Subsection "$bool = $internals->_register_callback( name => CALLBACK_NAME, code => CODEREF );"
Registers a callback for later use by the internal libraries.
.PP
Here is a list of the currently used callbacks:
.IP "install_prerequisite" 4
.IX Item "install_prerequisite"
Is called when the user wants to be \f(CW\*(C`asked\*(C'\fR about what to do with
prerequisites. Should return a boolean indicating true to install
the prerequisite and false to skip it.
.IP "send_test_report" 4
.IX Item "send_test_report"
Is called when the user should be prompted if he wishes to send the
test report. Should return a boolean indicating true to send the 
test report and false to skip it.
.IP "munge_test_report" 4
.IX Item "munge_test_report"
Is called when the test report message has been composed, giving
the user a chance to programatically alter it. Should return the 
(munged) message to be sent.
.IP "edit_test_report" 4
.IX Item "edit_test_report"
Is called when the user should be prompted to edit test reports
about to be sent out by Test::Reporter. Should return a boolean 
indicating true to edit the test report in an editor and false 
to skip it.
.IP "proceed_on_test_failure" 4
.IX Item "proceed_on_test_failure"
Is called when 'make test' or 'Build test' fails. Should return
a boolean indicating whether the install should continue even if
the test failed.
.IP "munge_dist_metafile" 4
.IX Item "munge_dist_metafile"
Is called when the \f(CW\*(C`CPANPLUS::Dist::*\*(C'\fR metafile is created, like
\&\f(CW\*(C`control\*(C'\fR for \f(CW\*(C`CPANPLUS::Dist::Deb\*(C'\fR, giving the user a chance to
programatically alter it. Should return the (munged) text to be
written to the metafile.
.ie n .Sh "$bool\fP = \f(CW$internals\->_add_to_includepath( directories => \e@dirs )"
.el .Sh "\f(CW$bool\fP = \f(CW$internals\fP\->_add_to_includepath( directories => \e@dirs )"
.IX Subsection "$bool = $internals->_add_to_includepath( directories => @dirs )"
Adds a list of directories to the include path.
This means they get added to \f(CW@INC\fR as well as \f(CW$ENV{PERL5LIB}\fR.
.PP
Returns true on success, false on failure.
.ie n .Sh "$id = CPANPLUS::Internals\->_last_id"
.el .Sh "\f(CW$id\fP = CPANPLUS::Internals\->_last_id"
.IX Subsection "$id = CPANPLUS::Internals->_last_id"
Return the id of the last object stored.

.el .Sh "\f(CW$id\fP = CPANPLUS::Internals\->_store_id( \f(CW$internals\fP )"
.IX Subsection "$id = CPANPLUS::Internals->_store_id( $internals )"
Store this object; return its id.
.ie n .Sh "$obj\fP = CPANPLUS::Internals\->_retrieve_id( \f(CW$ID )"
.el .Sh "\f(CW$obj\fP = CPANPLUS::Internals\->_retrieve_id( \f(CW$ID\fP )"
.IX Subsection "$obj = CPANPLUS::Internals->_retrieve_id( $ID )"
Retrieve an object based on its \s-1ID\s0 \*(-- return false on error.
.ie n .Sh "CPANPLUS::Internals\->_remove_id( $ID )"
.el .Sh "CPANPLUS::Internals\->_remove_id( \f(CW$ID\fP )"
.IX Subsection "CPANPLUS::Internals->_remove_id( $ID )"
Remove the object marked by \f(CW$ID\fR from storage.
.ie n .Sh "@objs = CPANPLUS::Internals\->_return_all_objects"
.el .Sh "\f(CW@objs\fP = CPANPLUS::Internals\->_return_all_objects"
.IX Subsection "@objs = CPANPLUS::Internals->_return_all_objects"
Return all stored objects.
