hi thomas ...
Is it a good idea to install that in /usr[/local]/lib/flext, or should this rather be in */share/flext or /usr/local/lib/pd/flext (which is not existing on OSX) ?
i think */share/flext would be a better place than */lib/flext ...
still, for the config files /usr is a bad place, since the files in /usr should be static. basically, that's what /var is for ... on the other hand, they are configuration files, which would imply /etc/flext ... still, i'd prefer /var ...
cheers ... tim
