[tex-live] yhmath confusion

[Ulrike Fischer]

While trying to answer a question on the miktex list I found out
that the yhmath package is quite confusing:

1. The search of CTAN point to
http://www.ctan.org/tex-archive/fonts/yhmath

(no dtx, no mf, but a sty and as type1 font a pfa, but no map-file) 

2. There are files also here
http://ctan.org/tex-archive/macros/latex/contrib/yhmath/

(dtx and so mf but no type1 font)

3. And TeXLive 2013 includes a pfb and map-file. But I couldn't find
out its source
2013/texmf-dist/fonts/type1/public/yhmath/yhcmex.pfb
2013/texmf-dist/fonts/map/dvips/yhmath/yhmath.map

Could someone sort this out? Where do the pfb and the map in TL 2013
come from?

(I really miss the file search on CTAN)
