Yes, I assumed this.

Downloading it from the unstable repository and using

   dpkg -i <downloadfile>

would be the most simple solution.  I personally add unstable to my
sources.list but you need to tweak /etc/apt/preferences somehow like
this:

Package: *
Pin: release a=stable
Pin-Priority: 501

Package: *
Pin: release a=unstable
Pin-Priority: 50


ATTENTION: I have no idea whether NeuroDebian distribution name is
"stable"!

Once you have done so you can drop a file
    /etc/apt/preferences.d/01-lintian.pref
with the content

Package: lintian
Pin: release a=unstable
Pin-Priority: 601

and you will get always the latest lintian.

There are people who strongly advise to replace the compressed files but
the minimum requirement is to have the uncompressed ones in addition.

I *tried* to work on this with no final success but providing sufficent
examples how to continue.  I admit when building I was running again in
test suite errors (see attached build logs) and thus I have not checked
the resulting linking (see debian/links).  Regarding the JS libraries:
You were in CC of my mail to debian-mentors about the bootstrap.min.js
mess.  Perhaps you need to follow strategy 1 as written above and provide
the source directly.  This is definitely true for mpld3.v0.2.min.js where
I did not found any package inside Debian.

You can steal the principle from the gnumed-client package:

   http://anonscm.debian.org/viewvc/debian-med/trunk/packages/gnumed-client/trunk/debian/

The copies of JS fiels are in debian/JS and if you seek for
`yui-compressor` you will see what needs to be done to compress the files.
BTW, if this is just a local documentation I probably would not even mind
about the compression and simply drop the uncompressed files into the
according locations.

... and here we have a final lintian error that needs to be dealt with.
At wiki.debian.org you find (hopefully) sufficient information how to
approach this.

Hope this helps

     Andreas.
