All\ncomputations are done exactly in either multiple  precision or fixed\ninteger arithmetic. Output is not stored in memory, so even problems\nwith very large output sizes can sometimes be solved.  The program is\nintended for Unix/Linux platforms, but will compile using gcc/cygwin on\nWindows.\n","package_architecture":"amd64","stem":"lrs","readme":null,"dependencies":[{"path":"devel/gmp","type":"library","package_spec":"","url":"/packages/current/devel/gmp/"},{"path":"devel/gmake","type":"build","package_spec":"","url":"/packages/current/devel/gmake/"}],"reverse_dependencies":{"count":0,"url":null},"categories":["math"],"flavors":[],"only_for_architectures":["aarch64","alpha","amd64","mips64","mips64el","powerpc64","riscv64","sparc64"],"not_for_architectures":[]}}
