Subject: [tldistro] tex4ht %%~ expands to $TEXMFDIST
Message-ID: <201903072258.x27MwWuF003697@freefriends.org>

TeX distro maintainers who package tex4ht: for TeX Live 2019,
the t4ht program will expand %%~ to $TEXMFDIST (set in texmf.cnf)
instead of $SELFAUTOPARENT. This means the tex4ht.env file should use
stuff like
  i%%~/tex4ht/ht-fonts/iso8859/1/!
instead of
  i%%~/texmf-dist/tex4ht/ht-fonts/iso8859/1/!

Perhaps distro versions have already been doing this, since
the SELFAUTOPARENT expansion was probably not useful, but I thought it
was worth mentioning.
