155645307a use partial strings for passing argv to toplevel.pl 
In run_top_level: rename variables, make them partial strings

The rename is mostly cosmetic: all of argv is passed, and if argv
contains flags, goals, etc, it's more than filenames.

Using partial strings instead of atom came from discussions about how to
pass goals in the CLI, and can thus be considered preliminary work for
that.

In toplevel.pl: convert partial string to atom before passing it to
`use_module`.

208927544d ADDED: provide a rudimentary version of portray_clause/1 
At the moment, library(format) seems to be a fitting place.
In the eventual library organization, portray_clause/1 and
related predicates may be moved to their own dedicated library.

partial_string/3 can be replaced by (=)/2 in this example.

8b1df2e9ca ADDED: CLP(ℤ), Constraint Logic Programming over Integers 
library(clpz) implements declarative integer arithmetic.

The most important predicates for reasoning about integers are:

    (#=)/2    equality
    (#\=)/2   disequality
    (#<)/2    less than
    (#>)/2    greater than
    (#=<)/2   less than or equal to
    (#>=)/2   greater than or equal to

In addition, the library provides several global constraints, such as
all_distinct/1 and global_cardinality/2, and reification predicates
that reflect the truth values of constraints into integer variables.

Enumeration predicates such label/1 and labeling/2 can be used to
search for solutions over finite domains.

Almost all Prolog programs also reason about integers. Therefore, I
recommend to add this library to your .scryerrc configuration file so
that declarative integer arithmetic is available in all your programs.
