| 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. |

| # The macOS native Tk (AKA Aqua Tk) and Tcl are most commonly |
| # built and installed as macOS framework bundles. However, |
| # for several reasons, we cannot take full advantage of the |
| # Apple-supplied compiler chain's -framework options here. |
| # Instead, we need to find and pass to the compiler the |
| # absolute paths of the Tcl and Tk headers files we want to use |
| # and the absolute path to the directory containing the Tcl |
| # and Tk frameworks for linking. |
| # |
| # We want to handle here two common use cases on macOS: |
| # 1. Build and link with system-wide third-party or user-built |
| # Tcl and Tk frameworks installed in /Library/Frameworks. |
| # 2. Build and link using a user-specified macOS SDK so that the |
| # built Python can be exported to other systems. In this case, |
| # search only the SDK's /Library/Frameworks (normally empty) |
| # and /System/Library/Frameworks. |
| # |
| # Any other use case should be able to be handled explicitly by |
| # using the options described above in detect_tkinter_explicitly(). |
| # In particular it would be good to handle here the case where |
| # you want to build and link with a framework build of Tcl and Tk |
| # that is not in /Library/Frameworks, say, in your private |
| # $HOME/Library/Frameworks directory or elsewhere. It turns |
| # out to be difficult to make that work automatically here |
| # without bringing into play more tools and magic. That case |
| # can be handled using a recipe with the right arguments |
| # to detect_tkinter_explicitly(). |
| # |
| # Note also that the fallback case here is to try to use the |
| # Apple-supplied Tcl and Tk frameworks in /System/Library but |
| # be forewarned that they are deprecated by Apple and typically |
| # out-of-date and buggy; their use should be avoided if at |
