I agree that some type of routine like David's FIND_RESOURCE_FILE is
extremely useful. Also, note that you can expand notation like '~' and
'..' using FILE_EXPAND_PATH:

IDL> $pwd
/Users/mgalloy/projects/idllib/src
IDL> print, file_expand_path('../..')
/Users/mgalloy/projects

FILEPATH doesn't just work for files in the IDL root folder.
Use the ROOT_DIR keyword to direct it anywhere you like.

I find File_Resource_File handy for locating any kind of
a file in any directory that is on the IDL path:
