The source cache option takes the same values as the cache option. The
|
|
|
958e1b |
documentation reads a little strange because it starts with "In contrast
|
|
|
958e1b |
the src_cache option ...". The fact that this is comparing with the
|
|
|
958e1b |
previous documented option (the 'cache' option) is implicit. Readers
|
|
|
958e1b |
may be confused, especially if they jump to src_cache without reading
|
|
|
958e1b |
cache documentation first.
