Just thought I'd make a list, since many people are not aware these tools exist.
1) MakeLRF
The first tool, released even before Sony's own LIBRIe addons. Converts a text file.

2) Sony's LIBRIe addons (mostly in Japanese, and mostly require LIBRIe):

3) flatLRF, a Java tool which can convert whole sites to an LRF book.

4) Book Creator, an official tool by Canon. Probably the most complete solution, however it is not distributed freely anymore.

5) lrs2lrf, a command-line tool which uses a DLL from Book Creator to compile a Xylog XML (BBeB source format) .lrs file into an .lrf

6) BookDesigner.
A multi-format conversion tool which can also output LRF files, using the same DLL from Book Creator.
