Context Format
--------------

   The context output format shows several lines of context around the
lines that differ.  It is the standard format for distributing updates
to source code.

   To select this output format, use the `-C LINES',
`--context[=LINES]', or `-c' option.  The argument LINES that some of
these options take is the number of lines of context to show.  If you
do not specify LINES, it defaults to three.  For proper operation,
`patch' typically needs at least two lines of context.
