is a companion program for which includes the following TEX-related tools:
TFtoPL
— Converts a TFM (TEX font metric) file into a PL (property list) file. The PL file will be created in the current folder; it is a human-readable version of the information stored in the TFM file. Apart from verifying the correctness of a TFM file, TFtoPL can also be used to modify the font metrics. For example, you can edit the PL file, change the amount of kerning between two characters, and run PLtoTF.
PLtoTF
— Converts a PL file into a TFM file. The TFM file will be created in the current folder.
VFtoVP
— Converts a VF (virtual font) file into a VPL (virtual property list) file. The VPL file will be created in the current folder; it is a human-readable version of the information stored in the VF file. VFtoVP also needs to read one or more TFM files from the folder path specified in the ``Set TFM folder'' dialog. (If you keep the application in the same folder as the TeX-fonts folder then you won't need to change the supplied path. Note that multiple search folders are not supported, so it's a good idea to keep all VF-related TFMs in the one folder. All of 's VF-related TFMs are currently kept in the PS sub-folder in TeX-fonts.)
VPtoVF
— Converts a VPL file into a VF file. The VF file will be created in the current folder. VPtoVF also creates a new TFM file in the folder specified by the ``Set TFM folder'' dialog.
provides some nice features for running these tools in a Mac environment. For example, the standard file dialog has a ``Do all files'' button which allows you to process all TFM/PL/VF/VPL files in the current folder. Background processing is supported. You can also delete PL/VPL files from within .
