Tighten up the specification of what counts as a code file. The previous

specification was too liberal in some areas and missing things in others.
This specification is based on the actual extensions found in the source
tree.

+# This script is a general purpose "apply" function for the source files in LLVM
+# It uses "find" to locate all the source files and then applies the user's 
+# command to them. As such, this command is often not used by itself much but
+# the other find related tools (countloc.sh,llvmgrep,getsrcs.sh) are all based 
+# on the implementation. This script defines "what is a source file" in LLVM and
+# so should be maintained if new directories, new file extensions, etc. are 
+# used in LLVM as it progresses.
+#
+# Usage:
+#  llvmdo [-dirs "DIRNAMES..." PROGRAM ARGS...
+#
+# The -dirs argument allows you to specify the set of directories that are 
+# searched. By default, everything is searched
+# (excluding certain things), runs "wc -l" on them to get the number of lines in
+# each file and then sums up and prints the total with awk. 
+#
+# The script takes no arguments but does expect to be run from the top llvm
+# source directory.
