[Libmesh-devel] Create parent directories of output files?

[Roy S. <roy...@ic...>]

Flipping through feature requests for a libMesh-based application, I
noticed this one: when output files with directory paths (e.g.
outputdirectory/outputsubdirectory/outputfile) are requested, and when
at runtime outputdirectory and/or outputsubdirectory don't yet exist,
they ought to be created.  (the current behavior is a
libmesh_file_error() exception)

Not sure when I'm going to get around to this item, but when I do,
would anyone find it useful as a libMesh feature?  If so, should it be
standard behavior, or default behavior that can be disabled with a
parameter to the write methods, or non-default behavior that can be
enabled with a parameter to the write methods?
