+ :type domainname: str
+ :rtype: unicode
+
+.. function:: check_domainname(domainname)
+
+ Returns the validated domain name *domainname*.
+
+ It also converts the name of the domain from IDN to ASCII, if necessary.

+ long or contains invalid characters.
+
+.. function:: exec_ok(binary)
+
+ Checks if the *binary* exists and if it is executable.
+
+ :param binary: path to the binary
+ :type binary: str
+ :rtype: str
+ :raise VirtualMailManager.errors.VMMError: if *binary* isn't a file
+ or is not executable.
+
+.. function:: expand_path(path)
+
+ Expands paths, starting with ``.`` or ``~``, to an absolute path.
+
+ :param path: Path to a file or directory
+ :type path: str
+ :rtype: str
+
+.. function:: get_unicode(string)
+
+ Converts `string` to `unicode`, if necessary.
+
+ :param string: The string taht should be converted
+ :type string: str
+ :rtype: unicode
+
+.. function:: idn2ascii(domainname)
+
+ Converts the idn domain name *domainname* into punycode.
+
+ :param domainname: the unicode representation of the domain name
+ :type domainname: unicode
+ :rtype: str
+
+.. function:: is_dir(path)
+
+ Checks if *path* is a directory.
+
+ :param path: Path to a directory
