6 # .epub is defined by the IDPF at www.idpf.org and is made up of 3 standards:
7 # - Open Publication Structure (OPS)
8 # - Open Packaging Format (OPF)
9 # - Open Container Format (OCF)
12 # -c, --css [FILE] Use FILE for CSS on generated XHTML.
13 # -d, --debug Show debugging output.
14 # -f, --font [OTF FILE] Embed OTF FILE in .epub.
15 # -h, --help Display usage info.
16 # -s, --stylesheet [XSL FILE] Use XSL FILE as a customization
17 # layer (imports epub/docbook.xsl).
18 # -v, --verbose Make output verbose.
