+MAIN FEATURES
+=============
+
+ Table of Contents
+ :=:=:=:=:=:=:=:=:
+ A. A Basic Literate Programming Environment
+ B. Other Basic Literate Programming Environments
+ C. Environments for Multi-Module Programs
+ D. Code and Documentation Produced from Same Specification
+ E. Examples B, C, D
+
+ Note: The code for the examples can be extracted from this file
+ by renaming this file to LitProg.tex and compiling the
+ file with TeX or LaTeX (the make files for Example C, however,
+ must be extracted mannually). The compilation puts the code
+ in files progA.tex, progB.tex, progC.tex, main.tex,
+ aux.tex, macros.tex, progC.sty, and progD.tex.
+
+A. A Basic Literate Programming Environment
+:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:
+
+ \input ProTex.sty
+ \AlProTex{EXT,<<<>>>,title,list,[],`}
+
+This environment adds to (La)TeX the following commands for handling code.
+
+a. Definitions of code fragments \<code title\><<<
+ code fragment>>>
+
+b. References to code segments `<code title`>
+
+c. Output files of code \OutputCode[EXTENSION]\<code title\>
+ `[EXTENSION]' is optional
+ when EXTENSION = EXT
+
+d. References to the character `
+ within code fragments ``
+
+Warning: Do not include 2 or more consecutive blank characters
+ in `<code title`>
+

+
+\OutputCode\<prog A\> \end{document}

+
+
+B. Other Basic Literate Programming Environments
+:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=
+
+a. Framing of code fragments can be requested with the option [[]]
+ in \AlProTex, e.g.,
+
+ \AlProTex{EXT,<<<>>>,title,list,[],`,[[]]}
+
+b. Framing of code titles can be avoided by removing the option []
+ from \AlProTex, e.g,
+
+ \AlProTex{EXT,<<<>>>,title,list,`}
+
+c. The characters @, |, and ? can also act as escape characters within
+ code fragments (e.g., replace all appearances of ` with @ in Example A).
+
+d. Line breaks within listing of code can be obtained with the command `NL%
+
+e. Comments within listing of code can be obtained with commands of
+ the form `%...`%
+
+f. The choice of code-delimiters <<< and >>> can be changed by placing
+ a command of the form \def\CodeDel{{open delimiter}{close delimiter}}
+ before \AlProTex.
+
+g. The following command requests that future \OutputCode commands identify
+ the titles of the different code fragments. (Other information, like
+ page numbers in documents and line numbers in source files, can also
+ be incorporated.)
+
+ \Comment{open-comment delimiter}{close-comment delimiter}
+
+PLEASE EXAMINE AND RUN EXAMPLE B
+
+
+C. Environments for Multi-Module Programs
+:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:
+
+Multi-module programs can be divided into independent (La)TeX files
+that can be compiled either separately or together. For instance,
+in Example C
+
+1. Three modules (main, aux, and macros) are defined independently
+ (in main.tex, aux.tex, macros.tex) and are connected through a
+ joint root file (progC.tex). The different files import a
+ common style file (progC.sty).
+
+ progC.tex Root file
+ main.tex LaTeX file for first module
+ aux.tex LaTeX file for second Module
+ macros.tex LaTeX file for third module
+ progC.sty Style file (imported by each of the above files)
+ make files Unix management programs
+
+2. The files can be compiled separately (latex main.tex, latex aux.main,
+ latex macros.tex) or jointly (latex progC.tex).
+
+3. To allow quick generation, compilation, and linkage of C-code files
+ (see, e.g., the make files), joint compilations do not revise code
+ files.
+
+4. Separate compilations use chapter/section/subsection/subsubsection/page
+ numbers that are collected in joint compilations.
+
+5. In joint compilations, each module ends with an index to its code titles.
+
+6. To allow nonrelated identical titles in different modules, and to
+ save on memory, previous definitions of code fragments are deleted at
+ the start of each module.
+
+PLEASE RUN AND EXAMINE EXAMPLE C
+
+D. Code and Documentation Produced from Same Specification
+:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:=:===
+
+Example D demonstrates how math formulas and their code can be generated
+from joint specifications.
+
+PLEASE EXAMINE AND RUN EXAMPLE D
+
+
