dnl	This file is an input file used by the GNU "autoconf" program to
dnl	generate the file "configure", which is run during Tcl installation
dnl	to configure the system for the local environment.
dnl 
dnl This file contains code to generate "tls" using either the
dnl OpenSSL libraries or libraries from the commercial BSAFE SSL-C
dnl product from RSA Security.  In the United States, it is necessary
dnl to use the RSA BSAFE libraries for any product developed for
dnl commercial use. Licensing information for BSAFE SSL-C may be
dnl obtained from RSA Data Scurity Inc., San Mateo, California, USA.
