Here is another script I wrote to quickly list title and author(s) of ePUB books. In the manner of mobils (in the MobiPerl suite), here is epubls.pl, use it on a file or several files ("epubls.pl *.epub" works) and get the title, author and number of pages (as calculated by ADE):
Code:
Title(s): William Tell Told Again
Author(s): P. G. Wodehouse (aut); Philip Dadd (ill); John W. Houghton (clb)
Pages: 57
