#
# 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.
