  var file = require("file");
## API ### file.walk(start, callback) Navigates a file tree, calling callback for each directory, passing in (null, dirPath, dirs, files). ### file.walkSync(start, callback) Synchronus version of file.walk, calling callback for each directory, passing in (dirPath, dirs, files). ### file.mkdirs(path, mode, callback) Makes all the directories in a path. (analgous to mkdir -P) For example given a path like "test/this/path" in an empty directory, mkdirs would make the directories "test", "this" and "path". ### file.mkdirsSync(path, mode) Like file.mkdirs but synchronous. ### file.path.abspath(path) Expands ".", "..", "~" and non root paths to their full absolute path. Relative paths default to being children of the current working directory. ### file.path.relativePath(root, fullPath) Given a root path, and a fullPath attempts to diff between the two to give us an acurate path relative to root. ### file.path.join(head, tail) Just like path.join but haves a little more sanely when give a head equal to "". file.path.join("", "tail") returns "tail", path.join("", "tail") returns "/tail"
