NAME
coala - a versatile compiler from action languages to answer set programs SYNOPSIS
coala [options]file[number] DESCRIPTION
This manual page documents briefly the coala command. coala is a versatile compiler from action languages to answer set programs. It supports different encodings, variables and LTL style queries. It translates an action language into a logic program under the answer set semantics. After being grounded by lparse or gringo, the logic program can be solved by an answer set solver such as clasp. At the moment coala is able to translate the action language AL, B, C, a subset of C+ and the action language CTAID. The type of input language can be specified with a command line option. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, see the potassco-guide. -h, --help Show summary of options. --version Show version of program. SEE ALSO
