+#
+# 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. Note that you must use quotes
+# around the list of directory names. After that 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.
