X
XThis installation shell script will examine your system and ask you questions
Xto determine how trn and its auxiliary files should be installed. If you
Xget stuck on a question, you may use a ! shell escape to start a subshell or
Xexecute a command. Many of the questions will have default answers in
Xsquare brackets--typing carriage return will give you the default.
X
XOn some of the questions which ask for file or directory names you are
Xallowed to use the ~name construct to specify the login directory belonging
Xto "name", even if you don't have a shell which knows about that. Questions
Xwhere this is allowed will be marked "(~name ok)".
X
XMuch effort has been expended to ensure that this shell script will run
Xon any Unix system. If despite that it blows up on you, your best bet is to
Xedit Configure and run it again. (Trying to install trn without having run
XConfigure is well nigh impossible.) Also, tell Wayne (davison@drivax.UUCP)
Xhow he blew it.
X
XThis installation script affects things in two ways: 1) it does direct
Xvariable substitutions on some of the files included in this kit, and
X2) it builds a config.h file for inclusion in C programs. You may edit
Xany of these files as the need arises after running this script.
