|
|
* silently ignores duplicates. The following command can be used for
|
|
* checking for duplicates:
|
|
* grep "=> '" Extension.php | cut -d\' -f2 | sort | uniq -d
|
|
* application/octet-stream is generally used as fallback when no other
|
|
* MIME-type can be found, but the array does not contain a lot of such
|
|
* unknown extension. One entry exists, though, to allow detection of
|
|
* file extension for this MIME-type.
