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#

39# Abort on command error.
