If no argument is given, behave as if the command line was -l {}.\n\nDo not recurse into subdirectories, only compile source code files directly contained in the named or implied directories.\n\nForce rebuild even if timestamps are up-to-date.\n\nDo not print the list of files compiled. If passed once, error messages will still be printed. If passed twice (-qq), all output is suppressed.\n\nDirectory prepended to the path to each file being compiled. This will appear in compilation time tracebacks, and is also compiled in to the byte-code file, where it will be used in tracebacks and other messages in cases where the source file does not exist at the time the byte-code file is executed.\n\nRemove the given prefix from paths recorded in the .pyc files. Paths are made relative to the prefix.\n\nThis option can be used with -p but not with -d.\n\nPrepend the given prefix to paths recorded in the .pyc files. Use -p / to make the paths absolute.\n\nThis option can be used with -s but not with -d.\n\nregex is used to search the full path to each file considered for compilation, and if the regex produces a match, the file is skipped.\n\nRead the file list and add each line that it contains to the list of files and directories to compile. If list is -, read lines from stdin.\n\nWrite the byte-code files to their legacy locations and names, which may overwrite byte-code files created by another version of Python. The default is to write files to their 3147 locations and names, which allows byte-code files from multiple versions of Python to coexist.\n\nControl the maximum recursion level for subdirectories. If this is given, then -l option will not be taken into account. python -m compileall -r 0 is equivalent to python -m compileall -l.\n\nUse N workers to compile the files within the given directory. If 0 is used, then the result of os.process_cpu_count will be used. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
