-The original src/Cantarell-Regular.sfd file has the master sources 
-as Cubic (PostScript) Bezier splines. There are temporary layers 
-and a 'Spiro' layer in this file, containing forms used to create 
-the master Cubic Bezier glyphs; the Spiro layer contains forms in 
-Spiro splines, and much of the original typeface design by Dave
-Crossland was done by drawing in Spiro splines. However today the
-master drawing spline format is Cubic Bezier, and Spiro splines
-are used to inform their creation. 
-
-The Cantarell-Regular.sfd file is the _master_ source, and was 
-used to generate the Cantarell-Bold.sfd which is now a hard fork. 
-
-All development occurs by making changes to these drawing files. 
-When OTF or TTF binaries are compiled, they are copied to the 
-Cantarell-*-OTF.sfd and Cantarell-*-TTF.sfd files and then a 
-build process applied.

 This means that there should be a 1:1 match between these files, 
-the OTF and TTF files in the otf/ and ttf/ directories, and the
-output of generating new OTF and TTF files from FontForge.

-The build process is simple; the Spiro and temp layers are removed, 
-in the case of TTF files all layers are converted to Quadratic from
-Cubic, and then all glyphs have the Simplify, Add Extrema, Round 
-to Int, and Correct Direction operations applied.

 In the future a build script will be developed to do this in an
 automated way, which will be important for adding OpenType
