PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

### otf/

Exported OTF instance font files, ready to use.

### README.md

This file.

### sources/

#### Current archtecture of design spaces

This directary contains all UFO sources, build scripts and design space file, that are used to generate the font files in *otf/*, *ttf/* and *vf/*.

~~~

Bitcount_Grid_Double4-COLRv1.designspace
Bitcount_Grid_Single4-COLRv1.designspace
Bitcount_Mono_Double4-COLRv1.designspace
Bitcount_Mono_Single4-COLRv1.designspace
Bitcount_Prop_Double4-COLRv1.designspace
Bitcount_Prop_Single4-COLRv1.designspace

~~~

The flags in sources/build.py decide which VF is building and which stage of the building process is exectuted.

**WARNING** Generating the 6 different Bitcount VF flavours of about 8Mb, each of the 6 design spaces needs over 22Gb of free space in the _masters/ folder for the 208 expanded pixel UFO’s files (3x2x12x2 + 2x2x2x2x2x2), each over 100Mb.

#### Earlier attempts

Earliers attempts to create a separate 8-axes COLRv1 disign space, each with 3 masters expanded the project to too many masters.

Generating the 6 different Bitcount VF flavours of about 8Mb, each of the 6 design spaces needs over 100Gb of free space in the _masters/ folder for the 873 expanded pixel UFO’s files (3x2x12x2 + 3x3x3x3x3x3, with 3 masters on the COLRv1 axes), each with a size over 100Mb.
