__init__(self,
val=None)
(Constructor)
Parse the environment variable setting Globus XIO debug,
setting attributes for 'level' and 'filename'
The name of the variable is GLOBUS_XIO_DEBUG The format is:
<level> [,[[#]<file
name>][,<flag>[,<timestamp_levels>]] Or at least that is
the official format. However, timestamp levels is not documented, and
"flags" seems irrelevant here, so only level and file name
are really used.
If provided 'val' is used as the value to parse, otherwise it is
fetched from the environment.
==> Extension: If GLOBUS_XIO_DEBUG has non-whitespace after
<level> then that part to the "," is interpreted as a
filename to read the real value from. The first line of that file is
the value used. This rule is *not* applied recursively to this
value.
