Chapter 9 - Update acronyms

[frafra]

Here is a way to see all the acronyms that have been used and for which we should have a description, given regex='[A-Z][A-Z0-9-]*[A-Z0-9]':

grep -Por "$regex" src/dmh_content/chapters/ | awk -F: '{print $2}' | sort | uniq -c | sort -nr

This is what I get with the current revision (87b1728):

A similar command can be used to generate the markdown table:

grep -Por "$regex" src/dmh_content/chapters/ | awk -F: '{print $2}' | sort -u | awk '{ print "| " $0 " |  |  |" }'
