6.5.1 The 't1utils' package in 'utils/t1utils' ---------------------------------------------- Here we use the distributed source tree 't1utils-src' with modifications documented in 'TLpatches/*' and a proxy build system consisting of 'configure.ac' and 'Makefile.am'. The fragment 'ac/withenable.ac' contains KPSE_ENABLE_PROG([t1utils]) specifying the module name without any dependencies, and supplies the configure option '--disable-t1utils'.
