I tried to tackle this issue down yesterday by using a combination of 
"licensecheck -r --copyright" and "/u/l/cdbs/licensecheck2dep5". 
"Should be mostly LGPL-2+ with some GPL-2+ files..." I thought.

Well, I was mostly right, but the resulting copyright template was 
nearly 4000 lines long. An estimated 90% of these were "License: 
LGPL-2+" stanzas with partially only slightly varying combinations of 
Copyright holders. However, I wanted the new file to be in the same 
style as the copyright file we currently have in libav. That is 
"Files: *", then a list of *all* copyright holders, then "License: 
LGPL-2+" and then mention of the exceptions to this rule in separate 
stanzas. I tried to modify the licensecheck2dep5 script to match this 
need, but I have to admit that I am completely incapable of reading 
and writing Perl code and after short time my brain literally hurt.

Jonas, could you please help me and reveal how I have to modify the 
licensecheck2dep5 script to combine all Files and Copyright holders 
for which the same License applies into one single stanza?

Thanks!
