How to add or change Components, Properties, Values or Parameters


Adding or modifying values
---------------------------

You may have to modify these files or data structures

file design-data/value-c-types.txt
file design-data/prop-to-val.txt
table parameter_map[] in icalenums.c
enum icalvalue_kind in icalenum.h
table value_map[] in icalenums.c
enum icalparameter_value in icalenum.h
table propval_map[] in icalenums.c
function icalvalue_as_ical_string() in icalvalue.c
function icalvalue_new_from_string_with_error() in icalvalue.c

When you are done, if you changed any files in the design-data
directory, regnerate derived datatypes in src/libical with "make
derived" or "make icalvalue"
