NAME
    ToolSet - Load your commonly-used modules in a single import

VERSION
    This document describes ToolSet version 0.10

SYNOPSIS
    Creating a ToolSet:

         # My/Tools.pm
         package My::Tools;
 
         use base 'ToolSet'; 
 
         ToolSet->set_strict(1);
         ToolSet->set_warnings(1);
 
         ToolSet->export(
             'Carp'          => undef,       # get the defaults
             'Scalar::Util'  => 'refaddr',   # or a specific list
         );
 
         1; # modules must be true

    Using a ToolSet:

         # my_script.pl
 
         use My::Tools;
 
         # strict is on
         # warnings are on
         # Carp and refaddr are imported
 
         carp "We can carp!";
         print refaddr []; 

DESCRIPTION
    ToolSet provides a mechanism for creating logical bundles of modules
    that can be treated as a single, reusable toolset that is imported as
    one. Unlike CPAN bundles, which specify modules to be installed
    together, a toolset specifies modules to be imported together into other
    code.

    ToolSet is designed to be a superclass -- subclasses will specify
    specific modules to bundle. ToolSet supports custom import lists for
    each included module and even supports the `strict' and `warnings'
    pragmas, optionally enabling those pragmas when the ToolSet subclass is
    used.

    A ToolSet module does not physically bundle the component modules, but
    rather specifies lists of modules to be used together and import
    specifications for each. By adding the component modules to a
    prerequisites list in a `Makefile.PL' or `Build.PL' for a ToolSet
    subclass, an entire dependency chain can be managed as a single unit
    across scripts or distributions that use the subclass.

INTERFACE
  Setting up

         use base 'ToolSet';

    ToolSet must be used as a base class.

  `export'

         ToolSet->export(
             'Carp' => undef,                    
             'Scalar::Util' => 'refaddr',
         );

    Specifies packages and arguments to import via `use()'. An argument of
    `undef' or the empty string calls `use()' with default imports.
    Arguments should be provided either as a whitespace delimited string or
    in an anonymous array. An empty anonymous array will be treated like
    passing the empty list as an argument to `use()'. Here are examples of
    how how specifications will be provided to `use()':

         'Carp' => undef                 # use Carp; 
         'Carp' => q{}                   # use Carp;
         'Carp' => 'carp croak'          # use Carp qw( carp croak );
         'Carp' => [ '!carp', 'croak' ]  # use Carp qw( !carp croak );
         'Carp' => []                    # use Carp (); 

    Elements in an array are passed to `use()' as a white-space separated
    list, so elements may not themselves contain spaces or unexpected
    results will occur.

  `set_strict'

       ToolSet->set_strict(1);
       ToolSet->set_strict(0); # default

    Determines whether strict will enabled for modules that `use()' this
    one.

  `set_warnings'

       ToolSet->set_warnings(1);
       ToolSet->set_warnings(0); # default

    Determines whether warnings will enabled for modules that `use()' this
    one.

DIAGNOSTICS
    ToolSet will report an error for a module that cannot be found just like
    an ordinary call to `use()' or `require()'.

    Additional error messages include:

    *   `"Invalid import specification for MODULE"' -- an incorrect type was
        provided for the list to be imported (e.g. a hash reference)

CONFIGURATION AND ENVIRONMENT
    ToolSet requires no configuration files or environment variables.

DEPENDENCIES
    ToolSet requires at least Perl 5.6. ToolSet subclasses will, of course,
    be dependent on any modules they load.

INCOMPATIBILITIES
    The only pragmas that are explicitly supported are `strict' and
    `warnings', as these have a lexical scope and will not function properly
    if called from within the `eval' statement used for importing other
    modules. Other pragmas may or may not work depending on if they have a
    compile-time or run-time effect.

SEE ALSO
    Similar functionality is provided by the Toolkit module, though that
    module requires defining the bundle via text files found within
    directories in `PERL5LIB' and uses source filtering to insert their
    contents as files are compiled.

BUGS AND LIMITATIONS
    No bugs have been reported.
