# CS_CHECK_TEMPLATE_TOOLKIT2([EMITTER])
|
|
# Check if Template Toolkit 2 (http://www.tt2.org/) is available. The
|
|
# shell variable cs_cv_perl_tt2 is set to "yes" if the package is
|
|
# discovered, else "no". Also sets the shell variable TTREE to the name
|
|
# path of the 'ttree' utility program and invokes AC_SUBST(). If EMITTER
|
|
# is provided and the package was discovered, then
|
|
# CS_EMIT_BUILD_PROPERTY() is invoked with EMITTER in order to record the
|
|
# value of the TTREE variable in an output file. As a convenience, if
|
|
# EMITTER is the literal value "emit" or "yes", then
|
|
# CS_EMIT_BUILD_RESULT()'s default emitter will be used.
