Thanks for the repsonse and feedback!  I've appended a new patch at the
bottom of this message as well as replied to some of your comment inline.

Yeah, I was hoping somebody had a tool to make this faster :)  I wrote a
little script in guile and started working through it but its slow work.

I'm going on vacation next week so I might not be able to finish this
before then.

However it looks like Debian has a much more exhaustive listing of the
licenses here:
http://metadata.ftp-master.debian.org/changelogs/main/s/strongswan/strongswan_5.5.1-4+deb9u1_copyright

The 4 clause BSD licenses are troubling.  Apparently Debian doesn't
compile those files in their build.  Will have to investiate further.

For reference here's my shoddy guile script.

I agree I don't like the usage of "open source" but that's how they
brand themselves, not sure if it's right for me to change it to read
Free Software.  I took this sentence from their README file.

How about this?  I wrote this based upon the top features they list on
their homepage.

"StrongSwan is an IPsec implementation originally based upon
the FreeS/WAN project.  It contains support for IKEv1, IKEv2, MOBIKE, IPv6,
NAT-T and more."

> Oh, and: thanks for packaging StrongSwan!

NP :).
