# Change log

# 2018-11-25: Start. Copy from the project _Plu Glosa Nota_.
#
# 2018-11-27: Add asciidoctor-epub3, as an alternative to Pandoc. Replace the
# `$target` variable with a literal. Add a temporary cover, created by
# GraphicsMagick out of a text file.
#
# 2018-11-29: Add a pandoc EPUB stylesheet. Don't use asciidoctor-epub3
# anymore; use only pandoc. Fix pandoc's RTF and HTML output. Remove old <pic>
# directory link, which was used by HTML.
#
# 2019-02-23: Update pandoc parameters to version 2.6 and add templates. Make
# also a letter-size PDF. Make an alterntive EPUB with dbtoepub.
