The py_compile module provides a function to generate a
byte-code file from a source file, and another function used when the
module source file is invoked as a script.
Though not often needed, this function can be useful when installing
modules for shared use, especially if some of the users may not have
permission to write the byte-code cache files in the directory
containing the source code.
Exception raised when an error occurs while attempting to compile the file.
file[, cfile[, dfile[, doraise]]])
Compile a source file to byte-code and write out the byte-code cache
file. The source code is loaded from the file name file. The
byte-code is written to cfile, which defaults to file+'c' ('o' if optimization is enabled in the
current interpreter). If dfile is specified, it is used as
the name of the source file in error messages instead of file.
If doraise is true, a PyCompileError is raised when
an error is encountered while compiling file. If doraise
is false (the default), an error string is written to sys.stderr,
but no exception is raised.
Compile several source files. The files named in args (or on
the command line, if args is not specified) are compiled and
the resulting bytecode is cached in the normal manner. This
function does not search a directory structure to locate source
files; it only compiles files named explicitly.
When this module is run as a script, the main() is used to
compile all the files named on the command line.
