=head1 DESCRIPTION |
19
|
|
|
|
|
|
|
|
20
|
|
|
|
|
|
|
This module exports two functions, one to initialize the configuration of the |
21
|
|
|
|
|
|
|
packager, and the other to generate the exheres. Currently, this package only |
22
|
|
|
|
|
|
|
generates Exheres for Perl modules, but support for other languages is coming |
23
|
|
|
|
|
|
|
soon. |
24
|
|
|
|
|
|
|
|
25
|
|
|
|
|
|
|
An OO version of this module is also planned, since exporting things into the |
26
|
|
|
|
|
|
|
global namespace is icky. |
27

29
|
|
|
|
|
|
|
|
30
|
|
|
|
|
|
|
gen_template takes one argument, and that is the name of the perl module you |
31
|
|
|
|
|
|
|
wish to generate. It will output the exheres in your current directory, in a |
32
|
|
|
|
|
|
|
subdirectory named by the category it chooses. |
33
|
|
|
|
|
|
|
|
34
|
|
|
|
|
|
|
This will B<die> with an error if the exheres already exists. |

|

|

|

|
|
|
|
|
|
|
init_config can optionally take one argument, that being the location of the |
41
|
|
|
|
|
|
|
config file you wish to use for this run of the packager. Once run, it will get |
42
|
|
|
|
|
|
|
all of the configuration information for calls to C<gen_template()>. |
