Finds and returns the first node that matches the supplied xpath.
The context element
The xpath to search for. If not supplied or nil, returns the first node matching ‘*’.
If supplied, a Hash which defines a namespace mapping.
If supplied, a Hash which maps $variables in the query to values. This can be used to avoid XPath injection attacks or to automatically handle escaping string values.
XPath.first( node )
XPath.first( doc, "//b"} )
XPath.first( node, "a/x:b", { "x"=>"http://doofus" } )
XPath.first( node, '/book/publisher/text()=$publisher', {}, {"publisher"=>"O'Reilly"})
Performs a depth-first (document order) XPath search, and returns the first match. This is the fastest, lightest way to return a single result.

Adds tuple to the proxied TupleSpace. See TupleSpace#write.
Returns the first advertised TupleSpace.
Adds tuple
Whether this specification is stubbed - i.e. we have information about the gem from a stub line, without having to evaluate the entire gemspec file.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager instance to stand in for the class itself.

Installs the gem dep_or_name and all its dependencies. Returns an Array of installed gem specifications.
If the :prerelease option is set and there is a prerelease for dep_or_name the prerelease version will be installed.
Unless explicitly specified as a prerelease dependency, prerelease gems that dep_or_name depend on will not be installed.
If c-1.a depends on b-1 and a-1.a and there is a gem b-1.a available then c-1.a, b-1 and a-1.a will be installed. b-1.a will need to be installed separately.
Zlib::GzipWriter wrapper that gzips filename on disk.
Installs the gem and returns a loaded Gem::Specification for the installed gem.
The gem will be installed with the following structure:
@gem_home/ cache/<gem-version>.gem #=> a cached copy of the installed gem gems/<gem-version>/... #=> extracted files specifications/<gem-version>.gemspec #=> the Gem::Specification
Verifies that this gem:
Contains a valid gem specification
Contains a contents archive
The contents archive is not corrupt
After verification the gem specification from the gem is available from spec
