"The previous chapters discussed how to extend Python, that is, how to extend"
" the functionality of Python by attaching a library of C functions to it. "
"It is also possible to do it the other way around: enrich your C/C++ "
"application by embedding Python in it. Embedding provides your application "
"with the ability to implement some of the functionality of your application "
"in Python rather than C or C++. This can be used for many purposes; one "
"example would be to allow users to tailor the application to their needs by "
"writing some scripts in Python. You can also use it yourself if some of the"
" functionality can be written in Python more easily."
msgstr ""

"Embedding Python is similar to extending it, but not quite. The difference "
"is that when you extend Python, the main program of the application is still"
" the Python interpreter, while if you embed Python, the main program may "
"have nothing to do with Python --- instead, some parts of the application "
"occasionally call the Python interpreter to run some Python code."
msgstr ""
#: ../../extending/embedding.rst:26
msgid ""
"So if you are embedding Python, you are providing your own main program. "
"One of the things this main program has to do is initialize the Python "
"interpreter. At the very least, you have to call the function "
":c:func:`Py_Initialize`. There are optional calls to pass command line "
"arguments to Python. Then later you can call the interpreter from any part "
"of the application."
msgstr ""
#: ../../extending/embedding.rst:32
msgid ""
"There are several different ways to call the interpreter: you can pass a "
"string containing Python statements to :c:func:`PyRun_SimpleString`, or you "
"can pass a stdio file pointer and a file name (for identification in error "
"messages only) to :c:func:`PyRun_SimpleFile`. You can also call the lower-"
"level operations described in the previous chapters to construct and use "
"Python objects."

"Setting :c:member:`PyConfig.program_name` should be called before "

":c:func:`Py_FinalizeEx` call shuts the interpreter down, followed by the end"

"from another source, perhaps a text-editor routine, a file, or a database. "
"Getting the Python code from a file can better be done by using the "
