I got a little tired of manually extracting the html from epub
files when I wanted to just read the book in a browser. Just messing
around with bash I came up with a simple script to do the job.
Its pretty crude and I know I should have read the metadata.opf
and probably would have if I did this in Java or Python, anyway
thought I would share nonetheless. Works in linux, might work
on a mac with a few tweaks. Just pass in the epub file as the first
parameter.
