+ * lists.h - the LIST structure and routines to manipulate them
+ *
+ * The whole of jam relies on lists of strings as a datatype.  This
+ * module, in conjunction with newstr.c, handles these relatively
+ * efficiently.
+ *
+ * Structures defined:
+ *
+ *	LIST - list of strings
+ *	LOL - list of LISTs
+ *
+ * External routines:
+ *
+ *	list_append() - append a list onto another one, returning total
+ *	list_new() - tack a string onto the end of a list of strings
+ * 	list_copy() - copy a whole list of strings
+ *	list_sublist() - copy a subset of a list of strings
+ *	list_free() - free a list of strings
+ *	list_print() - print a list of strings to stdout
+ *	list_printq() - print a list of safely quoted strings to a file
+ *	list_length() - return the number of items in the list
+ *
+ *	lol_init() - initialize a LOL (list of lists)
+ *	lol_add() - append a LIST onto an LOL
+ *	lol_free() - free the LOL and its LISTs
+ *	lol_get() - return one of the LISTs in the LOL
+ *	lol_print() - debug print LISTS separated by ":"
+ *
+ * 04/13/94 (seiwald) - added shorthand L0 for null list pointer
+ * 08/23/94 (seiwald) - new list_append()
+ * 10/22/02 (seiwald) - list_new() now does its own newstr()/copystr()
+ * 11/04/02 (seiwald) - const-ing for string literals
+ * 12/09/02 (seiwald) - new list_printq() for writing lists to Jambase
