[Orgmode] configuring org-export-latex-classes

[Rainer Thiel]

I can't seem to find a way to configure the variable
org-export-latex-classes either directly (via customize-variable) or
through customizing a group.  customize-variable can't find this
variable, and I am unable to find the customizing group it may be in.
Some time (only a couple of weeks) ago I did successfully customize
that variable through a group for the life of me I now can't remember.

Can someone help me, please?

Many thanks in advance,

Rainer
