+OTHER NOTES:
+
+The epa_build configurations are still missing for certain packages.
+For example, a build of a strong-enough version of cmake so that it
+can support "https" downloads (sometimes required by epa_build itself)
+requires that cmake not use its weak internal curl library and instead
+use a fully configured external curl library. So the cmake epa_build
+should be configured with an external libcurl epa_build dependency,
+but that dependency does not exist yet. So I plan to use the
+directions (actually for the mingw-w64 fork of MinGW rather than for
+MinGW itself) in
+<http://www.gaia-gis.it/gaia-sins/mingw64_how_to.html> as a guide to
+create an epa_build configure for both libcurl and its openssl
+dependency. Note, that URL contains mingw-w64 build directions for a
+large number of free software packages so it may also be useful to
+solve some epa_build problems for some packages for the pango/cairo
+stack of libraries that currently have epa_build configuration
+problems for MinGW/MSYS.
+
+Also, it is becoming clear that many users are switching from the
+classical combination of MinGW and MSYS to the combination of
+mingw-w64 and MSYS2 (see <http://sourceforge.net/p/msys2/wiki/MSYS2
+installation/> for install directions for that newer version). Note
+that new platform cannot be currently tested on Wine because of
+<http://bugs.winehq.org/show_bug.cgi?id=35561> so my (AWI's)
+participation in such tests could only be indirect. Nevertheless, I
+would encourage such tests since apparently MSYS2 (a simplification of
+modern Cygwin) has fewer bugs and uses more up-to-date versions of
+software than the traditional MSYS (a simplification of ancient
+Cygwin).

+me to test PLplot against Qt5 (see recent list discussions concerning
+Qt5).
+* The qt4_lite build works fine on Linux but has not yet been tested on
+Windows.
+
+* The gtk+ complete stack of libraries (only required on Unix to
+satisfy a wxwidgets Unix dependency) builds fine on Linux. Part of
+these good Linux build results are for the pango/cairo subset of the
+gtk+ stack which is necessary on all platforms to support the "cairo"
+PLplot device driver and the libLASi library (necessary to support the
+psttf PLplot device driver). Unfortunately, the pango/cairo subset of
+gtk+ appears to have a number of build issues on Wine. I suspect most
+of those issues are not due to Wine bugs so I expect they will show up
+on Microsoft Windows as soon as someone attempts a build of pango or
+plplot (as opposed to plplot_lite) on that platform.
+
+* Currently epa_build has only been tested on Windows using my
+(extraordinarily slow) MinGW/MSYS/Wine platform for the plplot_lite
+case. The Wine developers view any deviation from Microsoft Windows
+behaviour as a Wine bug. So since it is unlikely that I am by
+accident taking advantage of some Wine bug to make this work, it
+should be trivial (and more than an order of magnitude faster than the
+Wine case) to follow what I have done for the MinGW/MSYS/Microsoft
+Windows case _if_ the bash.exe environment variable approach I
+document in cmake/epa_build/README is religiously followed. I also
+believe it should be straightforward to make the plplot_lite case work
+on the Cygwin platform, a mingw-w64/MSYS2 Windows platform, and a Windows
+platform consisting of the combination of MSYS (bash.exe and other
+MSYS tools are required for testing PLplot but will not be used for
+building it in this case) and MSVC. I have access to none of those
+platforms so volunteers are needed for this testing of epa_build for
+the plplot_lite case.
+
+* The epa_build of octave has not been configured. Octave has an
+enormous number of dependencies (much worse than PLplot), and I have
+no experience building octave. So I have decided to indefinitely put
+off working on this epa_build configuration. As a result, the octave
+component of the plplot epa_build is currently disabled both for
+plplot and plplot_lite, and it will likely be a long time before this
+limitation is removed unless someone else is motivated to
+make this work.
