1299 # This section contains definitions for functions that each ensure a
1300 # particular resource (a file, or a non-empty configuration variable for
1301 # example) is available, and if appropriate to extract default values
1302 # from pertinent package files.  Where a variable already has a non-
1303 # empty value (as set by the package's 'bootstrap.conf'), that value is
1304 # used in preference to deriving the default. Call them using their
1305 # associated 'require_*' variable to ensure that they are executed, at
1306 # most, once.
1307 #
1308 # Some of the require functions are very similar, so we generate those
1309 # as this file is sourced. They look complicated, but they are the same
1310 # as normal function declarations wrapped in "eval '<definition>'", so
1311 # that embedded single quotes need to be escaped, and wherever a symbol
1312 # is generated, we drop out of the single quotes and expand a variable
1313 # that holds the symbol.
1314 #
1315 # After that, the rest appear in asciibetical order.
