NAME

6       Module::Install::Can - Utility functions for capability detection
7

DESCRIPTION

9       "Module::Install::Can" contains a number of functions for authors to
10       use when creating customised smarter installers. The functions simplify
11       standard tests so that you can express your dependencies and conditions
12       much more simply, and make your installer much easier to maintain.

COMMANDS

15   can_use
16         can_use('Module::Name');
17         can_use('Module::Name', 1.23);
18
19       The "can_use" function tests the ability to load a specific named
20       module. Currently it will also actually load the module in the process,
21       although this may change in the future.
22
23       Takes an optional second param of a version number. The currently
24       installed version of the module will be tested to make sure it is equal
25       to or greater than the specified version.
26
27       Returns true if the module can be loaded, or false (in both scalar or
28       list context) if not.
29
30   can_run
31         can_run('cvs');
32
33       The "can_run" function tests the ability to run a named command or
34       program on the local system.
35
36       Returns true if so, or false (both in scalar and list context) if not.
37
38   can_cc
39         can_cc();
40
41       The "can_cc" function tests the ability to locate a functioning C
42       compiler on the local system. Returns true if the C compiler can be
43       found, or false (both in scalar and list context) if not.
44
45   can_xs
46         can_xs();
47
48       The "can_xs" function tests for a functioning C compiler and the
49       correct headers to build XS modules against the current instance of
50       Perl.
51

TO DO

53       Currently, the use of a "can_foo" command in a single problem domain
54       (for example "can_use") results in the inclusion of additional
55       functionality from different problem domains (for example "can_run").
56
57       This module should ultimately be broken up, and the individual
58       functions redistributed to different domain-specific extensions.
