 1 | Heroku buildpack: Perl
 2 | ======================
 3 | 
 4 | This is a Heroku buildpack that runs any PSGI based web applications using Starman.
 5 | 
 6 | Usage
 7 | -----
 8 | 
 9 | Example usage:
10 | 
11 |     $ ls
12 |     cpanfile
13 |     app.psgi
14 |     lib/
15 | 
16 |     $ cat cpanfile
17 |     requires 'Plack', '1.0000';
18 |     requires 'DBI', '1.6';
19 | 
20 |     $ heroku create --stack cedar --buildpack https://github.com/miyagawa/heroku-buildpack-perl.git
21 | 
22 |     $ git push heroku master
23 |     ...
24 |     -----> Heroku receiving push
25 |     -----> Fetching custom buildpack
26 |     -----> Perl/PSGI app detected
27 |     -----> Installing dependencies
28 | 
29 | The buildpack will detect that your app has an `app.psgi` in the root.
30 | 
31 | Libraries
32 | ---------
33 | 
34 | Dependencies can be declared using `cpanfile` (recommended) or more traditional `Makefile.PL`, `Build.PL` and `META.json` (whichever you can install with `cpanm --installdeps`), and the buildpack will install these dependencies using [cpanm](http://cpanmin.us) into `./local` directory.
