See ticket #7484 [1] for some effort to update the README.txt. A
related ticket is #8024 [2] for updating the scripts to check for
pre-requisites.

Usually, you should not do this. If you just want to build Sage, then
the following shell script suffices:

# script name: build.sh
1. #!/bin/sh
2. export DOT_SAGE=/tmp/<username>/<sage-x.z.y>
3. export MAKE='make -j<n>'
4. make

Line 2 sets the Sage configuration directory to the specified
directory. The default value is DOT_SAGE=$HOME/<username>. I often use
this script to build Sage as follows

$ chmod +x build.sh
$ nohup ./build.sh &
