# SYNOPSIS

# AX_PROG_NASM([ACTION-IF-NOT-FOUND])

# DESCRIPTION
#
# This macro searches for the NASM assembler and sets the variable "nasm"

# ACTION-IF-NOT-FOUND is not specified, configure will fail when the
# program is not found.

# Example:
#
# AX_PROG_NASM()
# AX_PROG_NASM([nasm_avail="no"])
