+dnl
+dnl The purpose of this infrastructure implementation is to provide a way
+dnl of giving host code access to the same set of assertions and tracing
+dnl facilities as are available on the target side. The implementations
+dnl of these facilities has to be rather different, for example the host
+dnl side has to worry about running in both command-line and GUI tools,
+dnl not to mention supporting different languages such as Tcl as well
+dnl as C and C++.
+dnl
+dnl After a successful build there should be a library libcyginfra.a
+dnl which can be linked with the application code and which can get
+dnl installed. In addition there will be a set of header files.
+dnl
+dnl The infrastructure exports four main header files:
+dnl
+dnl cyg/infra/cyg_type.h data types, useful macros, and a
+dnl few compiler-related odds and ends
+dnl
+dnl cyg/infra/cyg_ass.h lots of lovely assertion macros
+dnl
+dnl cyg/infra/cyg_trac.h lots of lovely trace macros
+dnl
+dnl cyg/infra/testcase.h routines for use in testcases
+dnl
+dnl These header files are shared between host and target side, to make
+dnl sure that a consistent set of macros is used between the two. There
+dnl are a number of host-specific extensions in the header files as
+dnl well.
+dnl
+dnl The header files rely on a number of other header files:
+dnl
+dnl pkgconf/infra.h
+dnl cyg/hal/basetype.h
+dnl
+dnl Obviously cyg/hal/basetype.h cannot be shared between host and target,
+dnl instead it has to depend on autoconf information.
+dnl
+dnl Sharing pkgconf/infra.h between host and target is slightly more feasible,
+dnl especially if we get the configuration tool to a point where it can
+dnl be used for both host and target. However for now this would create a
+dnl bit of confusion because two configuration systems would be in use, and
+dnl it seems better to stick with just autoconf for now. Therefore
+dnl pkgconf/infra.h #include's the file generated by autoconf and
+dnl generates the appropriate #define's (it is not a good idea to have
+dnl autoconf generate pkgconf/infra.h directly, autoconf is slightly too
+dnl eager to do substitutions).
+dnl
+dnl The configuration header file that is normally generated is
+dnl config.h. It is more in keeping with eCos conventions to have
+dnl a different header file hostinfra.h instead. This can
+dnl achieved using the appropriate AM_CONFIG_HEADER macro.
+dnl
+dnl Making the copies of cyg_type.h etc. is the responsibility of
+dnl Makefile.am, configure is responsible only for the makefile and for
+dnl hostinfra.h.
