[Fontconfig] Newbe that would like to contribute improvements

[Pander]

Hi all,

I'm a complete newby at configuring fontconfig and would like some
pointers on how to get started. I have a lot of information on fonts
that can be made better available in fontconfig and would like to be
able to add that in my fontconfig configuration and submit to this
project so more open and free fonts are supported better.

For example, I have a font that is made available like this:

fc-list : family style file|grep -i justus
Justus-Roman.ttf: Justus:style=Roman
Justus-Bold.ttf: Justus:style=Bold
Justus-Italic.ttf: Justus:style=Italic
Justus-Versalitas.ttf: Justus:style=Versalitas
Justus-Oldstyle.ttf: Justus:style=Oldstyle
Justus-ItalicOldstyle.ttf: Justus:style=ItalicOldstyle

What minimal configuration to I need to do add in /etc/fonts in order to
get this as output, see _text between underscores_ for changes:

fc-list : family style file|grep -i justus
Justus-Roman.ttf: Justus:style=Roman
Justus-Bold.ttf: Justus:style=Bold
Justus-Italic.ttf: Justus:style=Italic
Justus-Versalitas.ttf: Justus_ Versalitas_:style=_Roman_
Justus-Oldstyle.ttf: Justus_ Oldstyle_:style=_Roman_
Justus-ItalicOldstyle.ttf: Justus_ Oldstyle_:style=_Italic_

If someone would get me up to speed with this I can submit a series of
fixes and new additions. Note, I'm not too lazy to read the manual.
Because I'm new to this, I'm just looking on how to get started quickly
in a way that the developers can work with this as best as possible and
have fontconfig support more open and free fonts better.

Regards,

Pander
