fac6d54986 extend description of strings and partial strings 
Also, explain in more detail what this feature means to Prolog
application programmers, and the strategic direction of Scryer.

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.

Enjoy!

45d4f46024 main: skip args[0] 
This is a bit pedantic, it's unlikely that the executable would be
called `-v` or `--version`. However, it seems slightly more correct to
disregard argv[0] when checking flags.

896f2aeb74 main: add -v/--version flag 
Added a new dependency to take care of pulling in the version from git
at build time.

Args handling is minimalistic, but there wasn't any before, so I figured
this might do for now. (Eventually, some proper `--help` and usage
output might come in handy?)
