dnl Process this file with Autoconf to produce a configure script for Web2c.

dnl Some things are no longer configurable:
dnl - SMALL{TeX,MF,BibTeX}: too painful to maintain the separate patch
dnl files, and, for TeX, texmfmem.h would have to be fixed to support
dnl more than 256 fonts.
dnl - NONASCII: necessary for the character translation feature.
dnl - REGFIX: modern compilers mostly ignore register declarations, anyway.
dnl The code for these things remains (where applicable), so you can
dnl get these features if you are willing to hack the sources. If not,
dnl it'll take a good argument to convince me to invest the time to make
dnl them configurable.
dnl
dnl We don't use (for example) tex/tex.web because people who only want
dnl to build part of the distribution may not have any given program.
