Marser is a tool to parse MIB files written in SMIv1 and SMIv2. It deals with all the sections of a MIB module, namely, the IMPORTS, IDENTITY, TEXTUAL-CONVENTION, TRAP-TYPE, OBJECT-TYPE NOTIFICATION and conformance statements.
It has a small swing application to view the structure of a MIB file. An explorer like interface is used, presenting the node tree on the left and the node properties on the right.
