  10 # This script is a general purpose "apply" function for the source files in LLVM
  11 # It uses "find" to locate all the source files and then applies the user's
  12 # command to them. As such, this command is often not used by itself much but
  13 # the other find related tools (countloc.sh,llvmgrep,getsrcs.sh,userloc.sh) are
  14 # all based on this script.  This script defines "what is a source file" in
  15 # LLVM and so should be maintained if new directories, new file extensions,
  16 # etc. are used in LLVM as it progresses.
  17 #
  18 # Usage:
  19 #  llvmdo [-topdir DIR] [-dirs "DIRNAMES..."] [-code-only] PROGRAM ARGS...
  20 #
  21 # The -topdir option allows you to specify the llvm source root directly. If it
  22 # is not specified then it will be obtained with llvm-config which must be built
  23 # and in your path.
  24 #
  25 # The -dirs argument allows you to specify the set of directories that are
  26 # searched. The default list of directories searched is:
  27 #   include lib tools utils runtime autoconf docs test examples projects
  28 # Note that you must use quotes around the list of directory names.
  29 #
  30 # The -code-only option specifies that only those files that are considered
  31 # "code" should be visited. HTML documentation is considered code, but things
  32 # like README files, etc. are not.
  33 #
  34 # Finally, you simply specify whatever program you want to run against each
  35 # file and the arguments to give it. The PROGRAM will be given the file name
  36 # as its last argument.
