# Script 'mddia' requires 'java' in order to run 'ditaa' => 'yum install java'
# Script 'mddia' requires command 'dot' => 'yum install graphviz'
# Script 'mddia' requires Perl module 'rdfdot' => 'yum install perl-App-cpanminus && cpanm rdfdot'
# Optionally command 'pandoc -o out.pdf --latex-engine=xelatex' requires 'xelatex' installed by 'yum install texlive-xetec'

# 2. Replace case-insensitive line '% date' or '% xxx' by '%<doc_date>'

# (usefull if Markdown format uses extension "mmd_title_block"

# Note: All these replacements: - are case-insensitive
# - replace only the first occurence found in the file
