Release 0.3

In this new release I have created a Manual page with some nice formatting. And expanded on some of the options now providing more meaningful information. The man page can be seen by typing:

man ./script

In the future this would be added to the PATH so that it can be seen from any location the same with the actual script.

As for the script I have expanded the help section to provide the information given in the man page.
Also I have automated the retrieval of the pidora kernel that I was previously unable to do it because I had no idea how to construct the url that provided me with the source RPM.

Some other notes:
For the Pidora source RPM it only looks for packages in the f19-rpfr Tag when changing to f20-rpfr this line would need to be modified.
The -b option now will take 3.11 instead of 3.11.y, using 3.11.y will cause errors. It is better anyways to use 3.11 just simpler.
There is no error checking so if the information provided is not right it will not finish successfully.
Still no name for the script .... Poor nameless script.
 Since the scripts where getting too long I am instead linking to a file.

Man page:
https://drive.google.com/file/d/0B2G5T2vxJmLrUEhhZ1BrQ1JYWDA/edit?usp=sharing

Script:
https://drive.google.com/file/d/0B2G5T2vxJmLrTjJzcTNDeENEeDA/edit?usp=sharing


And I am off to Ecuador, it was great working on this. I will continue working on it when I return.
I plan on adding some error checking, some other useful options and cleaning up the the code more.

Release 0.2.1

Various bugfixes
Added email option to report when a new kernel is building - could not test it because bell blocks port 25
