ITF (Interlinear Text Formatter) is a set of TeX macros for typesetting interlinear texts. These macros can format an arbitrary number of aligning annotations with up to two freeform annotations. Programs are provided with the ITF package for converting output from IT or AMPLE into the format required by ITF. The ITF TeX macros can be used with either TeX 2.9 or TeX 3. A LaTeX style is provided as well as the plain TeX formatting definitions.

The MS-DOS programs require an 80386 or newer CPU.
