# be useful to your project, you should place a copy of it under
# version control in the top-level directory of your project. The
# intent is that all customization can be done with a bootstrap.conf
# file also maintained in your version control; gnulib comes with a
# template build-aux/bootstrap.conf to get you started.

# We also allow `LIBTOOLIZE', `M4', `SHA1SUM' and some others to be
# overridden, and export the result for child processes, but they are
# handled by the function `func_find_tool' and not defaulted in this

## Hookable functions. ##
## ------------------- ##
# After `bootstrap.conf' has been sourced, execution proceeds by calling

# `func_hookable func_name', you will find a matching `func_run_hooks
# func_name' which executes all functions added with `func_add_hook
# func_name my_func'.
#
# You might notice that many of these functions begin with a series of
# `$require_foo' lines. See the docu-comments at the start of the
# `Resource management' section for a description of what these are.
