  20 # Generate the init.c source file.
  21 #
  22 # Usage:
  23 #
  24 #    ./make-init-c source-files > init.c-tmp
  25 #
  26 # Where SOURCE-FILES is the list of source files to extract init functions from.
  27 #
  28 # Formatting conventions:  The name of the initialization routines must begin
  29 # with `_initialize_`, must start in column zero, and be followed with exactly
  30 # ` ()`.  For example:
  31 #
  32 # void
  33 # _initialize_foo ()
  34 # {
  35 #   ...
  36 # }
  37 #
  38
  39 # Abort on command error.
