# without expanding it.

UT_VAR=		value with ${UNEXPANDED} expression

.export-literal UT_VAR

.export-literal			# oops: missing argument

# After a variable whose value does not contain a '$' is exported, a following
# .export-literal can be skipped, to avoid a setenv call, which may leak
# memory on some platforms.
UT_TWICE_LITERAL=	value literal
.export UT_TWICE_LITERAL

# XXX: After an .export, an .export-literal has no effect, even when the
# variable value contains a '$'.

# After an .export, an .unexport resets the variable's exported state,
# re-enabling a later .export-literal.
