NAME
       Apache2::Const - Perl Interface for Apache Constants

Synopsis
	 # make the constants available but don't import them
	 use Apache2::Const -compile => qw(constant names ...);

	 # w/o the => syntax sugar
	 use Apache2::Const ("-compile", qw(constant names ...));

	 # compile and import the constants
	 use Apache2::Const qw(constant names ...);

Description
       This package contains constants specific to "Apache" features.

       mod_perl 2.0 comes with several hundreds of constants, which you don't
       want to make available to your Perl code by default, due to CPU and
       memory overhead. Therefore when you want to use a certain constant you
       need to explicitly ask to make it available.

       For example, the code:

	 use Apache2::Const -compile => qw(FORBIDDEN OK);

       makes the constants "Apache2::Const::FORBIDDEN" and
       "Apache2::Const::OK" available to your code, but they aren't imported.
       In which case you need to use a fully qualified constants, as in:

	 return Apache2::Const::OK;

       If you drop the argument "-compile" and write:

	 use Apache2::Const qw(FORBIDDEN OK);

       Then both constants are imported into your code's namespace and can be
       used standalone like so:

	 return OK;

       Both, due to the extra memory requirement, when importing symbols, and
       since there are constants in other namespaces (e.g., "APR::" and
       "ModPerl::", and non-mod_perl modules) which may contain the same
       names, it's not recommended to import constants. I.e. you want to use
       the "-compile" construct.

       Finaly, in Perl "=>" is almost the same as the comma operator. It can
       be used as syntax sugar making it more clear when there is a key-value
       relation between two arguments, and also it automatically parses its
       lefthand argument (the key) as a string, so you don't need to quote it.

       If you don't want to use that syntax, instead of writing:

	use Apache2::Const -compile => qw(FORBIDDEN OK);

       you could write:

	use Apache2::Const "-compile", qw(FORBIDDEN OK);

       and for parentheses-lovers:

	use Apache2::Const ("-compile", qw(FORBIDDEN OK));

Constants
