suppress references to archived mailing list items in wikis

As of today, there remain a number of hyperlinks in the wikis that refer to sympa archives:

pcbe13089:wikis$ find -type f -name '*.md' -exec grep 'msg[0-9]*.html' -H {}  \;|wc
     47     271    6503

These need to be replaced by references to attached copies of the involved messages. Note that uploading (=attachment) is done per-project, and it is here where the biggest nuisance lies.

Actually, the list is a bit shorter, if one takes out the KiCad references (stored in launchpad):

pcbe13089:wikis$ find -type f -name '*.md' -exec grep 'sympa.*msg[0-9]*.html' -H {}  \;

still, html files do not match the arctxt numbering, so a bit of scanning is required, plus the upload to projects is still largely manual. Anyway, it's doable with a bit of scripting and a bit of human brute force (the key word here is brute ).

Refining the data: project, file, url

pcbe13089:wikis$ find -type f -name '*.md' -exec grep 'sympa.*msg[0-9]*.html' -H {}  \;  | sed 's!\./\(\([^/]*\)\.wiki[^:]*\):.*\(http.*msg[0-9]*\.html\).*!\2 \1   \3!' |column -t
