     longDescription = ''
       For every symbol (type, function variable, or macro) that you use in
       foo.cc, either foo.cc or foo.h should #include a .h file that exports the
-      declaration of that symbol. The include-what-you-use tool is a program
-      that can be built with the clang libraries in order to analyze #includes
-      of source files to find include-what-you-use violations, and suggest
-      fixes for them. The main goal of include-what-you-use is to remove
-      superfluous #includes. It does this both by figuring out what #includes
-      are not actually needed for this file (for both .cc and .h files), and
+      declaration of that symbol.  The main goal of include-what-you-use is to
+      remove superfluous #includes, both by figuring out what #includes are not
+      actually needed for this file (for both .cc and .h files), and by
       replacing #includes with forward-declares when possible.
