DIRECTORY OVERVIEW:

minisat/mtl/            Mini Template Library
minisat/utils/          Generic helper code (I/O, Parsing, CPU-time, etc)
minisat/core/           A core version of the solver
minisat/simp/           An extended solver with simplification capabilities

================================================================================
BUILDING: (release version: without assertions, statically linked, etc)

 make r
 cp build/release/bin/mergesat <install-dir>/mergesat

Note: Mergesat can also be used via docker. The resulting docker image contains
a binary of mergesat that can be used to solve formulas (see examples below).

The docker file Dockerfile brings build dependencies for mergesat, and will
install the solver in the image, so that CNFs can be solved.

 docker build .

As the release build of mergesat is a statically linked binary, you can also use
the create container to compile the solver in the cloned repository.

Note, the binary created with the docker file tries to back allocated memory with
transparent huge pages. This typically results in a 10% speedup (average), but
also can result in less reproducability of runtime, as transparent huge pages
might not be available.

 docker run -u=$(id -u) -v $PWD:$PWD -w $PWD $CONTAINER make r -B

Full list of commands to build the solver with the docker file:

 CONTAINER=$(docker build -q .)
 docker run -u=$(id -u) -v $PWD:$PWD -w $PWD $CONTAINER make r -B
 cp build/release/bin/mergesat <install-dir>/mergesat

EXAMPLES:

Solve some CNF file:
 ./mergesat "input.cnf"

Solve some CNF file and produce an unsatisfiability proof:
 ./mergesat "input.cnf" -drup-file="$TMPDIR"/proof.out

Solve a CNF in a dockerfile:
docker run -v $PWD:$PWD $CONTAINER_ID \
  /opt/mergesat/uild/release/bin/mergesat $INPUT
