+development project.  Note that not all of the code is counted: for
+instance, the Makefiles and configure.in and autogen.sh are not counted. 
+Also, files that are automatically generated are not counted, nor are
+files that have been 'borrowed' from other projects. Also not counted 
+are experimental files, miscellaneous perl scripts, various translators,

+Note also that KLOC's are not a good metric of programmer productivity,
+nor even that <application>wc</application> is a good way of counting
+KLOC's.  Much better measures are complexity metrics, which, for
+example, count the number and size of if-then-else blocks, or the number
+and size of all blocks, or the number of math operators per each
+statement.  Maybe someday we'll run one of those tools on this code. 
+For now, this is what we have.
