The Rule File Editor is a tool to manage and edit contraction rule files.
Use the WinBraille Rule File Editor Ibrfe.exe to edit and compile WinBraille Rule Files.
To speed up the text conversion process, WinBraille uses a binary format of the rules. This binary format is created with a built-in compiler in the WinBraille Rule File Editor. The resulting binary file has the prefix ".ibk". The text file is embedded within the binary file and is automatically extracted when the binary file is opened in the WinBraille Rule File Editor.
