+      pmccabe calculates McCabe-style cyclomatic complexity for C and
+      C++ source code.  Per-function complexity may be used for
+      spotting likely trouble spots and for estimating testing
+      effort.
+
+      pmccabe also includes a non-commented line counter, decomment which
+      only removes comments from source code; codechanges, a program to
+      calculate the amount of change which has occurred between two source
+      trees or files; and vifn, to invoke vi given a function name rather
+      than a file name.
