Looks for a named sibling relative to the given path. If such a file

exists, its path will be returned, otherwise a second search will be
|
||
|
|
made for the named sibling relative to the path of the executable
|

currently running. This is useful in the case that something built
|

with py2exe, for example, needs to find data files relative to its

install. Note hence that care should be taken not to search for
|
||
|
|
private package files whose names might collide with files which might
|
||
|
|
be found installed alongside the python interpreter itself. If no
|
||

|
file is found in either place, the sibling relative to the given path
|

is returned, likely leading to a file not found error.
