# 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. Extract Tcl, Tk, and possibly extensions, version numbers from the
#    headers
# 7. Parse the OPTS macro value for user-specified build configuration
# 8. Parse the STATS macro value for statistics instrumentation
# 9. Parse the CHECKS macro for additional compilation checks

# 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.
