rlm@1 6 # This script will build a package based on the commands in $HOME/build.conf
rlm@1 7 # It can be called with the following parameters that
rlm@1 8 # will cause it to execute the respective *_commands() functions. If it is
rlm@1 9 # called with no parameter, that is equivalent to
rlm@1 10 # build unpack patch configure make check install clean
rlm@1 11 #
rlm@1 12 # It will create 8 log files in the $HOME directory:
rlm@1 13 # configure.log: All messages output during configure
rlm@1 14 # configure.err: Just the errors output during configure
rlm@1 15 # check.log: All messages output during checking
rlm@1 16 # check.err: Just the errors output during checking
rlm@1 17 # make.log: All messages output during make
rlm@1 18 # make.err: Just the errors output during make
rlm@1 19 # install.log: All messages output during make install
rlm@1 20 # install.err: Just the errors output during make install
rlm@1 21 #
rlm@1 22 # After running the script you should check the *.err files to see
rlm@1 23 # if any problems have occurred. If that is the case, use the corresponding
rlm@1 24 # *.log files to see the error messages in context.
