NAME

6       Panotools::Makefile::Rule - Assemble Makefile rules
7

SYNOPSIS

9       Simple interface for generating Makefile syntax
10

DESCRIPTION

12       Writing Makefiles directly from perl scripts with print and "\t" etc...
13       is prone to error, this library provides a simple perl interface for
14       assembling Makefile rules.
15

USAGE

17         my $rule = new Panotools::Makefile::Rule;
18
19       ..or additionally specify targets at creation time
20
21         my $rule = new Panotools::Makefile::Rule ('all');
22
23       A Makefile rule always has one or more 'targets', these are typically
24       filenames, but can be 'phony' non-files.
25
26       (phony targets should be listed as perequisites of the special .PHONY
27       target)
28
29         $rule->Targets ('output1.txt', 'output2.txt');
30
31       ..or equivalently:
32
33         $rule->Targets ('output1.txt');
34         $rule->Targets ('output2.txt');
35
36       Rules can have zero or more 'prerequisites', again these are typically
37       filenames, but can be 'phony' non-files.
38
39         $rule->Prerequisites ('input1.txt', 'input2.txt');
40
41       ..or equivalently:
42
43         $rule->Prerequisites ('input1.txt');
44         $rule->Prerequisites ('input2.txt');
45
46       Rules zero or more 'commands':
47
48         $rule->Command ('cp', 'input1.txt', 'output1.txt');
49         $rule->Command ('cp', 'input2.txt', 'output2.txt');
50
51       Assemble all this into string that can be written to a Makefile:
52
53         my $string = $rule->Assemble;
