Here's what I had originally prepare (script, but not automated):

% res/scripts/check-mime.pl --help
trunk-veryclean2/res/scripts/check-mime.pl version 1.1 calling 
Getopt::Std::getopts (version 1.05),
running under Perl version 5.8.4.
Usage:: res/scripts/check-mime.pl -m MIMEFILE -i INPUTFILE -o OUTPUTFILE
            MIMEFILE:   path to mime.types from the httpd project
            INPUTFILE:  path to existing web.xml, which will be checked
            OUTPUTFILE: path to the new (generated) web.xml. Any existing
                        file will be overwritten.

% res/scripts/check-mime.pl -m /shared/build/dev/httpd/svn/httpd \
     /path/to/mime.types -i conf/web.xml -o conf/web.xml-new
FATAL Definition 'flac' -> 'audio/x-flac' exists in mime.types but
FATAL differs from 'flac' -> 'audio/flac' in TOMCAT_ONLY.
FATAL You must either remove 'flac' from the TOMCAT_ONLY list to keep 
the mime.types variant,
FATAL or move it to TOMCAT_KEEP to overwrite the mime.types variant - 
Aborting!

OK, so that means we originally had "flac" in our web.xml, but httpd had 
none. In the meantime httpd added it as audio/x-flac, but we had 
audio/flac, so we need to decide between the two.

in httpd the change was (svn log):

r1301894 | fielding | 2012-03-17 09:58:59 +0100 (Sat, 17 Mar 2012) | 2 lines
Unregistered media types in common use, according to Wikipedia and MS

Doing a little search does not result in any of the two variants being 
obviously correct. So for now I add audio/flac to TOMCAT_KEEP and we 
stick to our decision (done in 1845472).

And then:

% res/scripts/check-mime.pl -m /shared/build/dev/httpd/svn/httpd \
     /path/to/mime.types -i conf/web.xml -o conf/web.xml-new
New file 'conf/web.xml-new' has been written.

% diff -u  conf/web.xmlconf/web.xml-new

No output, so no changes, nothing to update.

Regards,

Rainer
