* Very big makeover in the way telnet, telnetd and libtelnet are built.Mark Murray2003-07-161-1192/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there were two copies of telnet; a non-crypto version that lived in the usual places, and a crypto version that lived in crypto/telnet/. The latter was built in a broken manner somewhat akin to other "contribified" sources. This meant that there were 4 telnets competing with each other at build time - KerberosIV, Kerberos5, plain-old-secure and base. KerberosIV is no longer in the running, but the other three took it in turns to jump all over each other during a "make buildworld". As the crypto issue has been clarified, and crypto _calls_ are not a problem, crypto/telnet has been repo-copied to contrib/telnet, and with this commit, all telnets are now "contribified". The contrib path was chosen to not destroy history in the repository, and differs from other contrib/ entries in that it may be worked on as "normal" BSD code. There is no dangerous crypto in these sources, only a very weak system less strong than enigma(1). Kerberos5 telnet and Secure telnet are now selected by using the usual macros in /etc/make.conf, and the build process is unsurprising and less treacherous. Notes: svn path=/head/; revision=117675
