[tex-live] ngerman.sty - Undefined control sequence

[David Carlisle]

You can use

\input eplain
\let\zzz\DeclareTextSymbol
\let\DeclareTextSymbol\undefined
\input ngerman.sty
\let\DeclareTextSymbol\zzz

\bye


(\DeclareTextSymbol gets defined in the format in babel's hyphenation
code somewhere, and then eplain takes the  "latex branch" at one point
as it tests if that command is undefined to decide to use latex style
or plain style definitions)

This may not be the best fix but it's a usable workaround.
