Add manual page for program

[ExcaliburZero]

Currently the program does not have a manual page that can be shown via man jekyll-helper in order to provide quick information on the program. Thus, such as page should be added.

[ExcaliburZero]

These pages have some information on creating manual pages:

• Creating Your Own MAN Page Version 1.0
• HowTo: Linux / UNIX Create a Manpage

[ExcaliburZero]

It looks like the file for a manual pages is written something like the following.

.TH foo 1 "14 May 1999" "version 1.0"
.SH NAME
foo - my own text editor
.SH SYNOPSIS
.B [-d] [-e] [-f
.I filename
.B ]

It might be a good idea to see how manual pages are implemented in other programs such as Trimage.

[ExcaliburZero]

It looks like Trimage implements its manual page through the following:

• Commit: Add man page, by Kyrill Detinov
• Commit: add doc page, add it's author to the index.html,. fixes issue #17

The manual file should probably be licensed under the GNU Free Documentation License version 3.
