 Compiling programs that use the library
 ---------------------------------------
 The library consists of a folder full of C++ header files (`.hh') and source
-files (`.cc').  `#include' header files and compile with source files as
-necessary for your own programs.  A Makefile is included that compiles the
-library source files and the sample program and links them together; you can
-easily customize the Makefile to replace the sample with your own program, or

+files (`.cc').  Your own programs should `#include' the necessary header files
+and link with the source files.  A makefile that builds the sample program
+(`sample.cc') is included; you can adapt it to replace the sample with your own
+program.
+
+Alternatively, you can use your own build system or IDE.  In that case, you must
+put the library header files where the compiler will find them and arrange to
+have your program linked with the library source files; otherwise, you will get
+errors about missing header files or "undefined references".  To learn how to do
+this, consult the documentation for the build system or IDE; don't bother asking
+me.  Adding all the library files to your project will work in many IDEs but may
+not be the most desirable approach.
