# Genome::Sys(3pm)

System layer

## NAME

Genome::Sys  -  System layer

## VERSION

This document describes Genome::Sys version 0.05.

## SYNOPSIS

use Genome;

my `$dir` = Genome::Sys-\>dbpath('cosmic', 'latest');

## DESCRIPTION

Genome::Sys is a simple layer on top of OS-level concerns, including those automatically handled by the analysis system,  like database cache locations.

## METHODS

### swpath($name,$version)

Return the path to a given executable, library, or package.

This is a wrapper for the OS-specific strategy for managing multiple versions of software packages, (i.e. /etc/alternatives for Debian/Ubuntu)

The GENOME\_SW environment variable contains a colon-separated lists of paths which this falls back to. The default value is /var/lib/genome/sw/.

### dbpath($name,$version)

Return the path to the preprocessed copy of the specified database. (This is in lieu of a consistent API for the database in question.)

The GENOME\_DB environment variable contains a colon-separated lists of paths which this falls back to. The default value is /var/lib/genome/db/.
