+##===- utils/llvmdo - Counts Lines Of Code -------------------*- Script -*-===##
+# 
+#                     The LLVM Compiler Infrastructure
+#
+# This file is distributed under the University of Illinois Open Source
+# License. See LICENSE.TXT for details.
+# 
+##===----------------------------------------------------------------------===##
+#
+# 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,userloc.sh) are
+# all based on this script.  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 [-topdir DIR] [-dirs "DIRNAMES..."] [-code-only] PROGRAM ARGS...
+#
+# The -topdir option allows you to specify the llvm source root directly. If it
+# is not specified then it will be obtained with llvm-config which must be built
+# and in your path.
+#
+# The -dirs argument allows you to specify the set of directories that are 
+# searched. The default list of directories searched is:
+#   include lib tools utils runtime autoconf docs test examples projects
+# Note that you must use quotes around the list of directory names. 
+#
+# The -code-only option specifies that only those files that are considered 
+# "code" should be visited. HTML documentation is considered code, but things 
+# like README files, etc. are not.
+#
+# Finally, you simply specify whatever program you want to run against each 
+# file and the arguments to give it. The PROGRAM will be given the file name 
+# as its last argument.
