+# GHC Version

+# ProjectVersion    is treated as a *string*
+# ProjectVersionInt is treated as an *integer* (for cpp defines)
+
+# Versioning scheme: A.B.C
+#         A: major version, decimal, any number of digits
+#         B: minor version, decimal, any number of digits
+#	  C: patchlevel, one digit, omitted if zero.
+#
+# ProjectVersionInt does *not* contain the patchlevel (rationale: this
+# figure is used for conditional compilations, and library interfaces
+# etc. are not supposed to change between patchlevels).
+#
+# The ProjectVersionInt is included in interface files, and GHC
+# checks that it's reading interface generated by the same ProjectVersion
+# as itself. It does this even though interface file syntax may not 
+# change between versions.  Rationale: calling conventions or other 
+# random .o-file stuff might change even if the .hi syntax doesn't

+
+# A "platform" is the GNU cpu-type/manufacturer/operating-system target machine
+# specifier.  E.g. sparc-sun-solaris2
+#
+# Build  platform: the platform on which we are doing this build
+# Host   platform: the platform on which these binaries will run
+# Target platform: the platform for which this compiler will generate code
+#
+# We don't support build & host being different, because the build
+# process creates binaries that are run during the build, and also
+# installed.
+#
+# If host & target are different, then we are building a compiler
+# which will generate intermediate .hc files to port to the target
+# architecture for bootstrapping.  The libraries and stage 2 compiler
+# will be built as HC files for the target system, and likely won't
+# build on this host platform.
+#
+# An important invariant is that for any piece of source code, the
+# platform on which the code is going to run is the HOST platform,
+# and the platform on which we are building is the BUILD platform.
+# Additionally for the compiler, the platform this compiler will
+# generate code for is the TARGET.  TARGET is not meaningful outside
+# the compiler sources.
+#
+# Guidelines for when to use HOST vs. TARGET:
+#
+#  - In the build system (Makefile, foo.mk), normally we should test
+#    $(HOSTPLATFORM).  There are some cases (eg. installation), where
+#    we expect $(HOSTPLATFORM)==$(TARGETPLATFORM), so in those cases it
+#    doesn't matter which is used.
+#
+#  - In the compiler itself, we should test HOST or TARGET depending
+#    on whether the conditional relates to the code being generated, or
+#    the platform on which the compiler is running.  See the section
+#    on "Coding Style" in the commentary for more details.
+#
+#  - In all other code, we should be testing HOST only.
+#
+# NOTE: cross-compiling is not well supported by the build system.
+# You have to do a lot of work by hand to cross compile: see the
+# section on "Porting GHC" in the Building Guide.
