+Next, install it with `make install' (may require elevated
+user permissions).
+
+Finally, clean up the working directory through `make clean'.
+
+Customizing instructions
+------------------------
+The default character ('/') which separates the foreground
+from the background color may be redefined:
+
+`make FLAGS=-DCOLOR_SEP_CHAR_COLON' -> defines as ':'
+`make FLAGS=-DCOLOR_SEP_CHAR_SLASH' -> defines as '/'
+
+Debugging instructions
+----------------------
+For the sake of completeness, colorize can be also built with
+debugging output by issuing `make FLAGS=-DDEBUG'. The intention
+is to provide some memory allocation diagnostics (and might be
+extended in future). Usually, a debugging build is not required.
+
+Furthermore, tests can be run through valgrind by issuing, for
+example, `make check_valgrind 2>&1 | tee valgrind.out'. The
+file provided here for the `tee' invocation will be populated
+with the captured output from both standard output and error
+stream.
+
+Configuration File
+------------------
+A user configuration file may be populated with options and
+according values. See man page source file `colorize.1' for
+details.
