[erlang-questions] xsltproc - erl_doc runtime error: Variable 'stylesheet' has not been declared.

[borja.carbo@REDACTED]

Hi

You are completly right,

Not just stylesheet, but also winprefix, pdfname and logo seems to be  
compulsory.

I have discovered some interdependences with regards to values for the  
directory variables.

With the modifications (appended below) I managed to generate the  
documentation.

Is there anyway the same do not happen to other Erlang users?

Thanks and Best Regards / Borja
