currently we have no documentation as to what format the new parser accepts. As a matter of fact the documentation in the UsersGuide (see http://einsteintoolkit.org/documentation/UsersGuide/UsersGuidech7.html#x10-37000B3.2) is in contradiction with what the parser will allow:
* The parameter file is read sequentially from top to bottom, this means that if you set the value of a parameter twice in the parameter file, the second value will be used. * String parameter values can be specified either as unquoted tokens (not containing any whitespace), or as quoted values. If a quoted string parameter value spans multiple lines, all whitespaces, including newline characters, are preserved.
which will fail. Actually the first one is already incorrect with the current implementation which does not allow a parameter to be set twice (since this is often a sign of a user error).
While this is "just" documentation, I'll still flag it as major since the parser is so fundamental.
