A simple bash function to display a poem. 

Pull the function from the .cfg into your .bash_profile by adding this line to your bash profile:

. ~/.haiku.cfg

Poems are to be stored in a textfile with one line per poem. A forward slash indicated a new line e.g.

This is line 1 of the first poem / This is line 2 of the first poem
This is line 1 of the second poem / This is line 2 of the second poem

The bash function grabs a random poem and echoes it out line-by-line.

The function is called 'printhaiku', it takes one parameter: the poem file. 

In my .bash_profile I have put the following line to display a poem every time I open a new shell:

printhaiku ~/haiku.txt

I've added an example poem file.
