Subject: [PATCH] Rework text to introduce definition of CCS.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CCS ultimately wasn't mentioned until much later in the GPLv3 sections,
where, ironically, we have to point out that GPLv3 defined the term as
"Corresponding Source" [0], not CCS, and explain why GPL enforcement
wonks still say CCS.

This rework now introduces the acronym at the natural moment: while
describing GPLv2ยง3's use of the words "complete" and "corresponding".

Adding that made the section even more disjoint than it already was.  I
put in some \subsection's to make it slightly less so, and did some
wordsmith work on surrounding text.

[0] I wish some GPLv3 drafter had asked me what to call the defined term
     so that I could point out what fit standard parlance. :)

+Based on the appearance of those two words, GPL theorists will often refer to
+the source code required under the previsions of this section as ``Complete,
+Corresponding Source'', sometimes abbreviated as CCS\@.  CCS is not a formal,
+defined term in GPLv2, but rather, GPL theorists coined the acronym CCS to
+embody not just the concepts of ``complete'' and ``corresponding'' as found
+in GPLv2, but the entirety of GPLv2's requirements for source code
+provisioning.  In other words, GPL theorists might say: ``the company
+provided some source, but it wasn't CCS'', which would mean the source code
+failed in some ways to meet some term of GPLv2.

-Furthermore, GPLv2~\S3 is defending against a tactic that has in fact been
-seen in GPL enforcement.  Under GPL, if you pay a high price for
-a copy of GPL'd binaries (which comes with corresponding source, of
-course), you have the freedom to redistribute that work at any fee you
-choose, or not at all.  Sometimes, companies attempt a GPL-violating
-cozenage whereby they produce very specialized binaries (perhaps for
-an obscure architecture).  They then give source code that does
-correspond, but withhold the ``incantations'' and build plans they
-used to make that source compile into the specialized binaries.
-Therefore, GPLv2~\S3 requires that the source code include ``meta-material'' like
-scripts, interface definitions, and other material that is used to
-``control compilation and installation'' of the binaries.  In this
-manner, those further down the distribution chain are assured that
-they have the unabated freedom to build their own modified works
-from the sources provided.
+Indeed, CCS needs completely include not just that source which is directly
+translated by the compiler into object code, but other materials necessary to
+convert the source into equivalent binaries.  Specifically, GPLv2~\S3
+requires that the source code include ``meta-material'' like scripts,
+interface definitions, and other material that is used to ``control
+compilation and installation'' of the binaries.  In this manner, those
+further down the distribution chain are assured that they have the unabated
+freedom to build their own modified works from the sources provided.

+This requirement is not merely of theoretical value.  If you pay a high price
+for a copy of GPL'd binaries (which comes with CCS, of course), you have the
+freedom to redistribute that work at any fee you choose, or not at all.
