+# Nmake is a pretty weak environment in syntax and capabilities

+# the following parts.
+#
+# 0. Sanity check that compiler environment is set up and initialize
+#    any built-in settings from the parent makefile
+# 1. First define the external tools used for compiling, copying etc.
+#    as this is independent of everything else.
+# 2. Figure out our build structure in terms of the directory, whether
+#    we are building Tcl or an extension, etc.
+# 3. Determine the compiler and linker versions
+# 4. Build the nmakehlp helper application
+# 5. Determine the supported compiler options and features
+# 6. Parse the OPTS macro value for user-specified build configuration
+# 7. Parse the STATS macro value for statistics instrumentation
+# 8. Parse the CHECKS macro for additional compilation checks
+# 9. Extract Tcl, and possibly Tk, version numbers from the headers
+# 10. Based on this selected configuration, construct the output
+#     directory and file paths
+# 11. Construct the paths where the package is to be installed
+# 12. Set up the actual options passed to compiler and linker based
+#     on the information gathered above.
+# 13. Define some standard build targets and implicit rules. These may
+#     be optionally disabled by the parent makefile.
+# 14. (For extensions only.) Compare the configuration of the target
+#     Tcl and the extensions and warn against discrepancies.
+#
+# One final note about the macro names used. They are as they are
+# for historical reasons. We would like legacy extensions to
+# continue to work with this make include file so be wary of
+# changing them for consistency or clarity.
+
