Find the full path to the executable for gem name. If the exec_name is not given, an exception will be raised, otherwise the specified executable’s path is returned. requirements allows you to specify specific gem versions.
The mode needed to read a file as straight binary.
Returns a list of paths matching glob that can be used by a gem to pick up features from other gems. For example:
Gem.find_files('rdoc/discover').each do |path| load path end
if check_load_path is true (the default), then find_files also searches $LOAD_PATH for files as well as gems.
Note that find_files will return all files even if they are from different versions of the same gem. See also find_latest_files
Finds the user’s home directory.
Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. The hook is called after the gem has been extracted and extensions have been built but before the executables or gemspec has been written. If the hook returns false then the gem’s files will be removed and the install will be aborted.
Adds a hook that will get run after Gem::Specification.reset is run.
Safely read a file in binary mode on all platforms.
Is this a windows platform?
Find the ‘rubygems_plugin’ files in the latest installed gems and load them
The default directory for binaries
Allows toggling Windows behavior. This method is available when requiring ‘rubygems/test_case’
Start a dRuby server locally.
The new dRuby server will become the primary server, even if another server is currently the primary server.
uri is the URI for the server to bind to. If nil, the server will bind to random port on the default local host name and use the default dRuby protocol.
front is the server’s front object. This may be nil.
config is the configuration for the new server. This may be nil.
See DRbServer::new.

Stop the local dRuby server.
This operates on the primary server. If there is no primary server currently running, it is a noop.

Registers server with DRb.
This is called when a new DRb::DRbServer is created.
If there is no primary server then server becomes the primary server.
Example:
require 'drb' s = DRb::DRbServer.new # automatically calls regist_server DRb.fetch_server s.uri #=> #<DRb::DRbServer:0x...>

Copies a file system entry src to dest. If src is a directory, this method copies its contents recursively. This method preserves file types, c.f. symlink, directory… (FIFO, device files and etc. are not supported yet)
Both of src and dest must be a path name. src must exist, dest must not exist.
If preserve is true, this method preserves owner, group, and modified time. Permissions are copied regardless preserve.
If dereference_root is true, this method dereference tree root.
If remove_destination is true, this method removes each destination file before copy.

This method removes a file system entry path. path might be a regular file, a directory, or something. If path is a directory, remove it recursively.

Returns whether or not the entry point func can be found within the library lib in one of the paths specified, where paths is an array of strings. If func is nil , then the main() function is used as the entry point.
If lib is found, then the path it was found on is added to the list of library paths searched and linked against.
