what is a .ph file

I was just going thru some perl tutorial I came across 'h2ph' utility 
which converts c header files to .ph files

Ok man h2ph would give this much information , but what is the use of 
h2ph. When I have the need of any modules I create Packages and 
'require' or 'use'. I never till now required to include any .ph files.

     Are they required for perl development ( so that some geeks can 
change the source and recompile perl )

thanks
