/*
* Parse a data base entry. Entries may span multiple
* lines. An entry starts on a left margin. All subsequent
* lines must be indented by white space. An entry consists
* of tuples of the forms:
* attribute-name
* attribute-name=value
* attribute-name="value with white space"
*
* The parsing returns a 2-dimensional structure. The first
* dimension joins all tuples. All tuples on the same line
* form a ring along the second dimension.
