EmbeddedPkg: Extend NvVarStoreFormattedLib LIBRARY_CLASS

[mirror_edk2.git] / AppPkg / Applications / Python / Python-2.7.2 / Tools / scripts / diff.py

""" Command line interface to difflib.py providing diffs in four formats:\r
\r
* ndiff:    lists every line and highlights interline changes.\r
* context:  highlights clusters of changes in a before/after format.\r
* unified:  highlights clusters of changes in an inline format.\r
* html:     generates side by side comparison with change highlights.\r
