#This script is a dedicated to the creator of ebook-speaker
#Jos Lemmens / http://jlemmens.nl/ This Script takes no code
#from the original but intends to provide quick and easy way
#of outputing text to speach and saving the progress of a
#text file via a bookmark. it intends to be extreemly portable,
#only requring a shell, awk, seq, and espeak ideally you can
#replace espeak with any other tts which excepts pipe input.

#tested in bash, sh, yash, dash

#limitations, its not curses, or termcap so it cant accept
#keyboard interupts (yet), like going back, etc.

#count the lines / wc
#output lines, one by one to stdout awk
#pipe output to espeak awk | espeak
#print line numbers echo variable

#TODO: bookmarking more than one "converted" book
#will probably overwrite teh previous bookmark.
