##Task 1: create perl-5.20 RPM
Download latest perl 5.20.0 and create an RPM package for CentOS 6.5 i386/x86_64.
You'll need to setup local CentOS (Vagrant could be useful here), install rpmbuild, and createrepo utilities, write perl-5.20.0.el6.spec file to build your own perl-5.20.0.el6.{arch}.rpm.
After all your spec files should be commited to this GitHub repo :)
Warining: Note, that CentOS comes with perl-5.10.1 and new package should be installed to /opt/.
###Materials
For reference: perl-5.18.2-299.fc21.src.rpm contains both sources and spec file to needed to build package. Could be passed directly to rpmbuild tool.
