Sure.  But the ECW license is in RTF and the MrSID license is in PDF.

I suppose pdftotext and catdoc do a good enough job to produce plain text from

Sure, but I feel that it somewhat belittles the free licenses.

Same license.  Same file content.  Same md5sum.   In that case we could have
just determine which packages share the same license by md5sum and display each
license only once with a list of packages that share it.

But unfortunately the md5sums don't match in setup.ini although the licenses
are virtually the same (except for the FSF address, blanks, formfeeds and stuff
like that).  So that doesn't work.

Some of the free packages don't even contain the full license text and only
reference the well known license (e.g. available form OSI,
http://opensource.org/licenses/).   So the current license files could be well
replaced with a pointer to that site.

Any maybe there should be another field in the setup.ini that tells us if a
license must be explicitly accepted.

Ok, I'll do that tomorrow then.

Question is if that's a better approach for the osgeo4w installer or not.
