+# -*- makefile -*-
+# The file Setup is used by the makesetup script to construct the files
+# Makefile and config.c, from Makefile.pre and config.c.in,
+# respectively. Note that Makefile.pre is created from Makefile.pre.in
+# by the toplevel configure script.
+
+# (VPATH notes: Setup and Makefile.pre are in the build directory, as
+# are Makefile and config.c; the *.in files are in the source directory.)
+
+# Each line in this file describes one or more optional modules.
+# Modules configured here will not be compiled by the setup.py script,
+# so the file can be used to override setup.py's behavior.
+# Tag lines containing just the word "*static*", "*shared*" or "*disabled*"
+# (without the quotes but with the stars) are used to tag the following module
+# descriptions. Tag lines may alternate throughout this file. Modules are
+# built statically when they are preceded by a "*static*" tag line or when
+# there is no tag line between the start of the file and the module
+# description. Modules are built as a shared library when they are preceded by
+# a "*shared*" tag line. Modules are not built at all, not by the Makefile,
+# nor by the setup.py script, when they are preceded by a "*disabled*" tag
+# line.
+
+# Lines have the following structure:
+#
+# <module> ... [<sourcefile> ...] [<cpparg> ...] [<library> ...]
+#
+# <sourcefile> is anything ending in .c (.C, .cc, .c++ are C++ files)
+# <cpparg> is anything starting with -I, -D, -U or -C
+# <library> is anything ending in .a or beginning with -l or -L
+# <module> is anything else but should be a valid Python
+# identifier (letters, digits, underscores, beginning with non-digit)
+#
+# (As the makesetup script changes, it may recognize some other
+# arguments as well, e.g. *.so and *.sl as libraries. See the big
+# case statement in the makesetup script.)
+#
+# Lines can also have the form
+#
+# <name> = <value>
+#
+# which defines a Make variable definition inserted into Makefile.in
+#
+# The build process works like this:
+#
+# 1. Build all modules that are declared as static in Modules/Setup,
+# combine them into libpythonxy.a, combine that into python.
+# 2. Build all modules that are listed as shared in Modules/Setup.
+# 3. Invoke setup.py. That builds all modules that
+# a) are not builtin, and
+# b) are not listed in Modules/Setup, and
+# c) can be build on the target
+#
+# Therefore, modules declared to be shared will not be
+# included in the config.c file, nor in the list of objects to be
+# added to the library archive, and their linker options won't be
+# added to the linker options. Rules to create their .o files and
+# their shared libraries will still be added to the Makefile, and
+# their names will be collected in the Make variable SHAREDMODS. This
+# is used to build modules as shared libraries. (They can be
+# installed using "make sharedinstall", which is implied by the
+# toplevel "make install" target.) (For compatibility,
+# *noconfig* has the same effect as *shared*.)
+#
+# NOTE: As a standard policy, as many modules as can be supported by a
+# platform should be present. The distribution comes with all modules
+# enabled that are supported by most platforms and don't require you
+# to ftp sources from elsewhere.
+

+# Edit the definitions below to indicate which options you are using.

+\`configure' configures python 3.10 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+SUMMARY = """
+Python is an interpreted, interactive, object-oriented programming
+language. It is often compared to Tcl, Perl, Scheme or Java.
+
+Python combines remarkable power with very clear syntax. It has
+modules, classes, exceptions, very high level dynamic data types, and
+dynamic typing. There are interfaces to many system calls and
+libraries, as well as to various windowing systems (X11, Motif, Tk,
+Mac, MFC). New built-in modules are easily written in C or C++. Python
+is also usable as an extension language for applications that need a
+programmable interface.
+
+The Python implementation is portable: it runs on many brands of UNIX,
+on Windows, DOS, Mac, Amiga... If your favorite system isn't
+listed here, it may still be supported, if there's a C compiler for
+it. Ask around on comp.lang.python -- or just try compiling Python
+yourself.
