Defines the class RCS, which represents a directory with rcs version files and (possibly) corresponding work files. i����Nt RCSc B s e Z d Z e j e j d Z d � Z d � Z d d � Z d � Z d � Z d � Z d � Z d d d � Z d d d � Z d d � Z d � Z d � Z d � Z d � Z d � Z d d d � Z d � Z d � Z d � Z d d � Z d � Z d � Z RS( s7 RCS interface class (local filesystem version). An instance of this class represents a directory with rcs version files and (possible) corresponding work files. Methods provide access to most rcs operations such as checkin/checkout, access to the rcs metadata (revisions, logs, branches etc.) as well as some filesystem operations such as listing all rcs version files. XXX BUGS / PROBLEMS - The instance always represents the current directory so it's not very useful to have more than one instance around simultaneously s -_=+c C s d S( s Constructor.N( ( t self( ( s) /usr/lib64/python2.7/Demo/pdist/rcslib.pyt __init__& s c C s d S( s Destructor.N( ( R ( ( s) /usr/lib64/python2.7/Demo/pdist/rcslib.pyt __del__* s t c C si | j | d | � } | j � } | j | � } | rH | d | } n | d d k re | d } n | S( sm Return the full log text for NAME_REV as a string.
