NAME

6       Module::Install::External - Specify dependencies on external non-Perl
7       things
8

DESCRIPTION

10       "Module::Install::External" provides command that allow you to
11       declaratively specify a dependency on a program or system that is not
12       Perl.
13
14       The commands it provides are similar to those in Module::Install::Can,
15       except that they implement an explicit dependency, in addition to just
16       working out if the particular thing is available.
17

COMMANDS

19   requires_external_cc
20         requires_external_cc;
21
22       The "requires_external_cc" command explicitly specifies that a C
23       compiler is required in order to build (at make-time) the distribution.
24
25       It does not take any params, and aborts the Makefile.PL execution in a
26       way that an automated installation or testing system will interpret as
27       a "NA" ("not applicable to this platform") result.
28
29       This maybe be changed to an alternative abort result at a later time.
30
31       Returns true as a convenience.
32
33   requires_external_bin
34         requires_external_bin 'cvs';
35
36       The "requires_external_bin" command takes the name of a system command
37       or program, similar to the "can_run" command, except that
38       "requires_external_bin" checks in a way that is a declarative explicit
39       dependency.
40
41       The takes a single param of the command/program name, and aborts the
42       "Makefile.PL" execution in a way that an automated installation or
43       testing system will interpret as a "NA" ("not applicable to this
44       platform") result.
45
46       Returns true as a convenience.
47

TO DO

49       Work out how to save the external dependency metadata, in agreement
50       with the larger Perl community.
51
52       Implement the agreed external dependency metadata solution.
