                     13:
                     14: This is a string packages that uses a tree-based representation.
                     15: See cord.h for a description of the functions provided.  Ec.h describes
                     16: "extensible cords", which are essentially output streams that write
                     17: to a cord.  These allow for efficient construction of cords without
                     18: requiring a bound on the size of a cord.
                     19:
                     20: de.c is a very dumb text editor that illustrates the use of cords.
                     21: It maintains a list of file versions.  Each version is simply a
                     22: cord representing the file contents.  Nonetheless, standard
                     23: editing operations are efficient, even on very large files.
                     24: (Its 3 line "user manual" can be obtained by invoking it without
                     25: arguments.  Note that ^R^N and ^R^P move the cursor by
                     26: almost a screen.  It does not understand tabs, which will show
                     27: up as highlighred "I"s.  Use the UNIX "expand" program first.)
                     28: To build the editor, type "make cord/de" in the gc directory.
                     29:
                     30: This package assumes an ANSI C compiler such as gcc.  It will
                     31: not compile with an old-style K&R compiler.
