The documentation package I'm packaging is (for jessie+1):
http://pocoproject.org/releases/poco-1.4.7/poco-1.4.7-all-doc.tar.gz


the minimized libraries are:

$ tar --wildcards -tvf poco-doc_1.4.7.orig.tar.gz poco-1.4.7-all-doc/js/\*.js
-rw-rw-rw- guenter/staff  2171 2014-10-22 18:19 poco-1.4.7-all-doc/js/CollapsibleLists.compressed.js
-rwxrw-rw- guenter/staff  6636 2014-10-22 18:19 poco-1.4.7-all-doc/js/iframeResizer.contentWindow.min.js
-rwxrw-rw- guenter/staff  5571 2014-10-22 18:19 poco-1.4.7-all-doc/js/iframeResizer.min.js
-rw-rw-rw- guenter/staff 44790 2014-10-22 18:19 poco-1.4.7-all-doc/js/prettify.js

prettify.js is not minimized but following the Policy 4.13, it is also a
embedded code copie.


Upstream sources for libraries:

* http://code.stephenmorley.org/javascript/collapsible-lists/
  No tarball, license CC0, non minimized version available.

* https://github.com/davidjbradshaw/iframe-resizer
  Tarball available, license MIT, gruntfile.js file to build minimized
  version.
  Gruntjs (similar to ruby-rake) is not in Debian. Two options: use
  node-uglify in debian/rules, or package Gruntjs in another package
  again. It's probably better to make a package for Gruntjs.

* https://code.google.com/p/google-code-prettify/
  Tarball available, license Apache 2.0, Makefile to build minimized
  version, uses yui-compressor to minimize. In fact,
  poco-1.4.7-all-doc.tar.gz uses only a part of prettify.js (a file from
  an old 2007 version, revision 20, I don't know why).


Well, if I understand, the best way is:
* Three packages for the three libraries.
* One package for Gruntjs.
* Request to POCO authors to provide a tarball without minimized libraries OR remove it myself, making a dfsg package.

I'm right ?
