I have an interpreter name (say "Python") and an interval of versions (say "2.5 - 2.6").
Based on this data I need to select the python executable among installed files, if available. The rule of the "game" is that I write a data file (preferably in RDF/Turtle format) which describes all available version of Python (and other interpreters). My question is advice how to do it, in a practical way. For example, if I understand correctly /usr/bin/python on some systems may mean Python 2.x and on some systems Python 3.x. Is there any "standard" to avoid such multiple meanings of an executable located in the same path of the filesystem? In Debian, are there always more specific paths like /usr/bin/python2.7 or /usr/bin/python3.1? Also, does it make sense to parse output of `dpkg -p`? or is it better to write RDF config files manually? -- Victor Porton - http://portonvictor.org
