There is no specific installation procedure to follow for SPLinT, although
there are a few dependencies to keep in mind. To build all the tools
in the package, you will need the usual suite of build tools (gcc,
make and friends), bison and flex (which usually come separately),
cweb and cwebmac.tex (supplied by the texlive-extra-utils in Mint, 
for example), and various fonts (cyrillic, such as lhr10, etc., found in
texlive-lang-cyrillic, and extra sizes of Computer Modern, supplied by
texlive-fonts-extra). The only purpose for the cyrillic fonts is to supply
a decent looking pair of `french quotes' or `guillemot's used in 
./tex/btokenset.sty

The setup involved is minimal, but for the build procedure to work,
all the style files (that reside in ./tex and ./cweb) should be visible 
to \TeX\ (i.e. you should be able to \input them). Building everything
from scratch also requires Perl to be installed (see the scripts in the
./scripts directory). Building after the result of `make mostlyclean'
requires a C compiler and CWEB only.

* A note about make: while using make to perform quick rebuilds after
  minor modifications mostly works, this style of project in not very
  suitable for the capabilities makes supplies. Make is really good at
  codifying the build procedures that form a tree. In the case of
  SPLinT, the same commands often have to be run several times. What
  is even worse, running those commands repeatedly modifies the
  prerequisites for earlier targets. Thus, view make as simply a
  convenient way of recording every step needed to build the project
  and its various parts, not as an efficient building tool: it is
  always safer to say 'make distclean' and repeat the build.
