##===----------------------------------------------------------------------===##
#
# 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.
