# After configure completes, it has a better idea of some of the

# with bootstrap, so set those here where they can still be over-
# ridden by the user, but otherwise take precedence.

## Resource management. ##
## -------------------- ##

# This section contains definitions for functions that each ensure a
# particular resource (a file, or a non-empty configuration variable for
# example) is available, and if appropriate to extract default values
# from pertinent package files.  Where a variable already has a non-
# empty value (as set by the package's 'bootstrap.conf'), that value is
# used in preference to deriving the default. Call them using their
# associated 'require_*' variable to ensure that they are executed, at
# most, once.
#
# Some of the require functions are very similar, so we generate those
# as this file is sourced. They look complicated, but they are the same
# as normal function declarations wrapped in "eval '<definition>'", so
# that embedded single quotes need to be escaped, and wherever a symbol
# is generated, we drop out of the single quotes and expand a variable
# that holds the symbol.
#
# After that, the rest appear in asciibetical order.
