/*
* 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_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()
