##===- utils/llvmdo - Counts Lines Of Code -------------------*- Script -*-===##
#
# The LLVM Compiler Infrastructure
#
# This file was developed by Reid Spencer and 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) 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.
