# SYNOPSIS
#
#   AX_TRILINOS_EPETRAEXT([, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   On success, adds "include Makefile.export.epetraext" statements to every
#   Automake file containing @INC_AMINCLUDE@. Requires that Trilinos was
#   configured with the --enable-export-makefiles option. When
#   ACTION-IF-NOT-FOUND is not specified, the default behavior is for
#   configure to fail.
