 The programs are (edit the appropriate section and record your name to claim it; once someone has claimed a program, it is considered unavailable for others in the class to do for core credit):
-====COMMAND-LINE ARGUMENTS====
+====command-line arguments====
 All of the programs should accept the following command-line arguments (check for program-specific additional ones as well in the appropriate section):
-  * **-h/-?** display usage information and exit
+  * **-h** display usage information and exit
   * **-V** display version information and exit
   * **-s "STRING"** specify STRING as value to process
-  * **-4** set nibble as processing unit size
+  * **-4** set nibble as processing unit/word size
-  * **-7** set byte as 7-bits
+  * **-7** set byte/word as 7-bits
-  * **-8** set byte as 8-bits (default)
+  * **-8** set byte/word as 8-bits (default)
   * **-n** no delimiter between processing units
-  * **-d 'CHAR'** use CHAR as delimiter between processing units
+  * **-d 'CHAR'** use CHAR as delimiter between processing units (space is default)
   * **-q** quiet, do not display anything to STDOUT
   * **-v** verbose, display more information to STDOUT
+====general program processing/usage====
+**__usage__:** the program takes delimiter-separated numeric values via specified filename, or as a string communicated via the command-line, or from STDIN, converts them and then displays the result as appropriate for the particular tool (considering delimited output as well; delimiter is set to a single space by default). The program terminates upon exhausting all of its input.
+====compiling===
+The Makefiles are set up for this, but you are basically to compile each program with the following compiler options:
+  * **-Wall** increased warning pickiness/verbosity
+  * **-Werror** treat warnings as errors
+  * **--std=c99** compile with C99 language standards
