  Access to the archive
$obj->from(SOURCE, OPTIONS)

    Read definitions from the specified SOURCE, which usually can be a filehandle or filename. The syntax used in the information SOURCE is archiver dependent.

    Not all archivers implement "from()", so you may want to check with "UNIVERSAL::can()" beforehand.

    example:

     use User::Identity::Archive::Some;
     my $a = User::Identity::Archive::Some->new('xyz');
     $a->from(\*STDIN) if $a->can('from');

DIAGNOSTICS
Error: $object is not a collection.

    The first argument is an object, but not of a class which extends User::Identity::Collection.

Error: Cannot load collection module for $type ($class).

    Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname.

Error: Creation of a collection via $class failed.

    The $class did compile, but it was not possible to create an object of that class using the options you specified.

Error: Don't know what type of collection you want to add.

    If you add a collection, it must either by a collection object or a list of options which can be used to create a collection object. In the latter case, the type of collection must be specified.

Warning: No collection $name

    The collection with $name does not exist and can not be created.
