         #     not necessarily a leap year
         #     dates with years less than YEAR0 will not be accepted
         #     NB: Garmin protocol dates start at 1990 January 1st
         #         Lowrance dates start at 1992 January 1st

##### properties of known file formats
#   indices as NAME,PROPERTY  where PROPERTY is
#
#    mode         I/O mode in {in, out, {in out}}
#    depends      optional dependencies as evaluable code (globals must be
#                  declared), returning 0 on failure
#    filetype     in {unique, single, data} meaning: only one possible type,
#                 several types but each file has only one, other situations
#    types        to be used only if there is a single mode or the types are
#                 the same for in and out: admissible types as a subset of
#                 $TYPES-{GR}; the order must be that imposed by the format
#                 on the data in the file, if there is such an order
#    io_types     to be used if the mode is {in out} and the admissible types
#                 for in and out are different: pair with list of in types
#                 and list of out types as described for "types"
#    GREls        defined if there is support for dealing with GR elements
#    MODE,params  list of parameter names
#    MODE,pdefts  list of default values (or "ERROR" if value must be supplied)
#                  aligned with	list of parameter names; missing default
#                  values treated as ""; to get the value of a global
#                  variable use global:VARNAME
#    param,PNAME  list with global variable to set, conversion code from
#                  (external) $val to (internal) $val, constraint on possible
#                  values using $val as local variable and global variables
#                  of previous parameters (in the order given in the list of
#                  names), and, except for Shapefile, widget description as
#                  used by proc GMSetupParams (gendials.tcl); parameters are
#                  first converted in the order of occurrence in the list;
#                  each constraint and global variable are then checked/set
#                  in the same order
