# This program converts DocBook documents into .epub files.
#
# Usage: dbtoepub [OPTIONS] [DocBook Files]
#
# .epub is defined by the IDPF at www.idpf.org and is made up of 3 standards:
# - Open Publication Structure (OPS)
# - Open Packaging Format (OPF)
# - Open Container Format (OCF)
#
# Specific options:
# -c, --css [FILE] Use FILE for CSS on generated XHTML.
# -d, --debug Show debugging output.
# -f, --font [OTF FILE] Embed OTF FILE in .epub.
# -h, --help Display usage info.
# -s, --stylesheet [XSL FILE] Use XSL FILE as a customization
# layer (imports epub/docbook.xsl).
# -v, --verbose Make output verbose.
