# Nmake is a pretty weak environment in syntax and capabilities
# so this file is necessarily verbose. It's broken down into
# 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. 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.
# 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.
# 0. Sanity check compiler environment
# Check to see we are configured to build with MSVC (MSDEVDIR, MSVCDIR or
# VCINSTALLDIR) or with the MS Platform SDK (MSSDK or WindowsSDKDir)

# ROOT - root of this module sources
# COMPATDIR - source directory that holds compatibility sources
# DOCDIR - source directory containing documentation files
# GENERICDIR - platform-independent source directory
# WIN_DIR - Windows-specific source directory
# TESTDIR - directory containing test files
# TOOLSDIR - directory containing build tools
# _TCLDIR - root of the Tcl installation OR the Tcl sources. Not set
# when building Tcl itself.
# _INSTALLDIR - native form of the installation path. For Tcl
# this will be the root of the Tcl installation. For extensions
# this will be the lib directory under the root.
# TCLINSTALL - set to 1 if _TCLDIR refers to
# headers and libraries from an installed Tcl, and 0 if built against
# Tcl sources. Not set when building Tcl itself. Yes, not very well
# named.
# _TCL_H - native path to the tcl.h file
#
# If Tk is involved, also sets the following
# _TKDIR - native form Tk installation OR Tk source. Not set if building
# Tk itself.
# TKINSTALL - set 1 if _TKDIR refers to installed Tk and 0 if Tk sources
# _TK_H - native path to the tk.h file
