-This directory contains several files for programs that are tutorial
-and/or useful. If you are new to CWEB, read "wc.w" first; it's a
-typical example of CWEB applied to system programming.
-
-The Makefile on this directory is a generic way to build applications
-written in CWEB. Say, for example, "make wc" to get an executable
-program "wc" from wc.w. Say "make wc.dvi" to get a printable listing
-of its documentation. The program "wc" is a slight improvement over
-UNIX's standard word-count utility. (Try it, for example, with "wc *".)
-
-The treeprint program, by Norman Ramsey, generates tree-structured
-representations of file hierarchies. To use it, say "make treeprint.run"
-and then
-   find dir -type p -print | sort | treeprint
-(on a UNIX system), where dir is a directory with interesting subdirectories.
-
-The wmerge program, by Silvio Levy, produces a single CWEB file from a
-given CWEB file and a change file. It expands any "web include" (@i)
-specifications in the original CWEB file. To use it, say "make wmerge.run"
-and then, e.g., "wmerge foo.w bar.ch > foobar.w". Both CTANGLE and
-CWEAVE already accept change files, so you need not merge anything yourself
-in normal day-to-day operations; but wmerge can be useful in connection with
-the spelling checker described below.
-
-If you intend to read the source code of CTANGLE and CWEAVE, you may
-well wish to read wmerge.w first, or the hardcopy version obtained from
-"make wmerge.dvi"; it is similar but much simpler.
-
-The extex and wordtest programs, by Don Knuth, are useful spellcheckers.
-After "make extex.run" say also "ln extex excweb"; this gives
-you two filter programs, extex and excweb, that remove extraneous
-material from TeX and CWEB source files, respectively. To use them,
-you can say for example
-   cat foo.w | excweb | spell
-(or replace "cat foo.w" with "wmerge foo.w bar.ch"). A similar pipeline
-for TeX files would be
-   cat foo.tex | extex | spell
-Even better is to replace "spell" by "wordtest /usr/local/lib/dict/words",
-if you have a suitable dictionary. One such dictionary in the public domain
-can be found in directory ~ftp/pub/dict at ftp.cs.stanford.edu, available
-via anonymous ftp. To make your own dictionary from given ones,
-   cat dict1 dict2 dict3 dict4 | wordtest > words
-is quick and effective. See the documentation of wordtest for more info.
-
-A file kspell.el that provides an emacs user interface to extex+excweb+wordtest
-also appears in this directory. (Somebody should write ELWEB...)
-
-The files xview_types.w and xlib_types.w are examples of @i (include) files
-that can be used when writing XView programs. They are based on the header
-files in OpenWindows Version 3.0.
-
-An example XView application appears in Knuth's program oemacs.w, which
-he uses for heavy emacsing. It's not very portable, but if you have
-OpenWindows3 and a Sun Type-4 keyboard you may like it as much as he does.
-(It replaces "emacstool".) The file oemacs.el goes with it.
