Summary description:  Metric files for the Computer Modern fonts

Announcement text:
 This update replaces the contents of https://ctan.org/tex-archive/cm/tfm/
 with the 75 TFM files generated from the official Computer Modern Metafont
 sources. These TFM files have been distributed since the beginning of

 Also, this cm/tfm/ directory previously contained some non-CM TFM files,
 namely dummy.tfm, manfnt.tfm, old_manfnt.tfm, and cmsa10.tfm. The first
 two are available elsewhere on CTAN, in their respective packages. The
 latter two we do not know the provenance of, but you can get them from
 the /obsolete CTAN tree if need be.
