   1 #!/bin/sh

   3 # This script scans the whole source code for symbols of the form
   4 # 'xxx(yyy' where:
   5 #        xxx is either DECLARE_DEBUG_CHANNEL or DEFAULT_DEBUG_CHANNEL
   6 #        yyy is a C identifier
   7 # It outputs on the standard output a sorted list of the
   8 # yyy identifiers found in the .c files.
   9 # Each identifier is reported once. Header files are not scanned.
  10 #
  11 # The script can be given an argument that specifies the files to be
  12 # searched according to the following scheme:
  13 #    - if the argument does not contain a slash (/), the script
  14 #      will search the tree rooted in the current directory for
  15 #      files that match that description. You can also pass
  16 #      wildcard arguments, but remember to quote them to prevent
  17 #      expansion by the shell
  18 #    - if the argument does contain a slash, only that file is
  19 #      searched
  20 #    - if no argument is given, the argument defaults to "*.c"
  21 #      that is, all C files are searched.
  22 #    - if more than one argument is given, only the listed files are
  23 #      searched. Note that in this case, the script will not
  24 #      attempt to find them in some subdirectories, but rather
  25 #      it will try to open them in the current directory.
  26 # Thus, if you want to disable the automatic searching when the file
  27 # name does not contain a /, either prefix the filename with ./
  28 # or add /dev/null as another argument.
