This script is for a Unix like OS.

Be sure to run me in a dir where there is enough place for the
sources unpacked (40 Mb will do; I will _not_ remove the bundle).

During the build, don't be afraid of some compiler warnings: these
are purely cosmetic ones, because the translation of Pascal in C
don't put extra braces when indenting if/else; or because D.E. Knuth 
and Silvio Levy have written the CWEB programs so that they can compile
even on pre-ANSI C compilers (old prototypes).

Don't worry: if something is really wrong, the build fails...

I will build in SAVE_SPACE mode, requiring the minimal amount of
place.

When files have to be installed, I will have to switch under root.
Once, for kerTeX install. Once, for the installation of dumps and
compiled fonts.

Don't run me as root now! (R.I.S.K. and the kerTeX package framework
will refuse.)
