--% Description of Messages
--% OpenAxiom messages are read from a flat file database and returned
--% as one long string. They are preceded in the database by a key and
--% this is how they are referenced from code. For example, one key is
--% S2IL0001 which means:
--% S2 Scratchpad II designation
--% I from the interpreter
--% L originally from LISPLIB BOOT
--% 0001 a sequence number
--% Each message may contain formatting codes and and parameter codes.
--% The formatting codes are:
--% %b turn on bright printing
--% %ceoff turn off centering
--% %ceon turn on centering
--% %d turn off bright printing
--% %f user defined printing
--% %i start indentation of 3 more spaces
--% %l start a new line
--% %m math-print an expression
--% %rjoff turn off right justification (actually ragged left)
--% %rjon turn on right justification (actually ragged left)
--% %s pretty-print as an S-expression
--% %u unindent 3 spaces
--% %x# insert # spaces
--% The parameter codes look like %1, %2b, %3p, %4m, %5bp, %6s where the
--% digit is the parameter number ans the letters following indicate
--% additional formatting. You can indicate as many additional formatting
--% qualifiers as you like, to the degree they make sense. The "p" code
--% means to call prefix2String on the parameter, a standard way of
--% printing abbreviated types. The "P" operator maps prefix2String over
--% its arguments. The "o" operation formats the argument as an operation
--% name. "b" means to print that parameter in
--% a bold (bright) font. "c" means to center that parameter on a
--% new line. "f" means that the parameter is a list [fn, :args]
--% and that "fn" is to be called on "args" to get the text. "r" means
--% to right justify (ragged left) the argument.
--% Look in the file with the name defined in $defaultMsgDatabaseName
--% above for examples.
