+# Each line takes the form:
+# name <type>=<val>,<val>.. <type>=<val> ...
+# Where type is one of:
+# u use-attribute
+# r relation-attribute )
+# p position-attribute
+# s structure-attribute
+# t truncation-attribute
+# c completeness-attribute
+#
+# Special value for relation:
+# o ordered. Tells the CCL parser to convert a ccl relation
+# to a bib-1 relation (1,2,..6).
+# Special value for structure:
+# pw phrase/word. The CCL parser will decide whether phrase or word
+# is needed. Phrase is used if term contain blanks; otherwise
+# Word is used.
+# Special value for truncation:
+# l Allow left truncation if ? is at left side of term.
+# r Allow right truncation if ? is at left side of term.
+# b Allow left&right truncation if ? is at left&right side of term.
+# n Set truncation explicitly to "none" if no ? is given.
