my $bool = $cb->_move( from => '/some/file', to => '/other/file' );

my $cont = $cb->_get_file_contents( file => '/path/to/file' );
my $version = $cb->_perl_version( perl => $^X );
DESCRIPTION
"CPANPLUS::Internals::Utils" holds a few convenience functions for CPANPLUS libraries.
METHODS
$cb->_mkdir( dir => '/some/dir' )
"_mkdir" creates a full path to a directory.
Returns true on success, false on failure.
$cb->_chdir( dir => '/some/dir' )
"_chdir" changes directory to a dir.
Returns true on success, false on failure.
$cb->_rmdir( dir => '/some/dir' );
Removes a directory completely, even if it is non-empty.
Returns true on success, false on failure.
$cb->_perl_version ( perl => 'some/perl/binary' );
"_perl_version" returns the version of a certain perl binary. It does this by actually running a command.
Returns the perl version on success and false on failure.
$cb->_version_to_number( version => $version );
Returns a proper module version, or '0.0' if none was available.
$cb->_whoami
Returns the name of the subroutine you're currently in.
_get_file_contents( file => $file );
Returns the contents of a file
$cb->_move( from => $file|$dir, to => $target );
Moves a file or directory to the target.
Returns true on success, false on failure.
$cb->_copy( from => $file|$dir, to => $target );
Moves a file or directory to the target.
Returns true on success, false on failure.
$cb->_mode_plus_w( file => '/path/to/file' );
Sets the +w bit for the file.
Returns true on success, false on failure.
$uri = $cb->_host_to_uri( scheme => SCHEME, host => HOST, path => PATH );
Turns a CPANPLUS::Config style "host" entry into an URI string.
Returns the uri on success, and false on failure
$cb->_vcmp( VERSION, VERSION );
Normalizes the versions passed and does a '<=>' on them, returning the result.
$cb->_home_dir
Returns the user's homedir, or "cwd" if it could not be found
$path = $cb->_safe_path( path => $path );
Returns a path that's safe to us on Win32 and VMS.
Only cleans up the path on Win32 if the path exists.
On VMS, it encodes dots to _ using "VMS::Filespec::vmsify"
($pkg, $version, $ext) = $cb->_split_package_string( package => PACKAGE_STRING );
Splits the name of a CPAN package string up into its package, version and extension parts.
For example, "Foo-Bar-1.2.tar.gz" would return the following parts:
Package: Foo-Bar
Version: 1.2
Extension: tar.gz
