latex build problem
I encounter errors in latex when building PS file (or PDF file).
I do not understand "(\end occurred inside a group at level 31)"
What should I look for for this error? I tried "-v" option in
debiandoc2latexpsand essentially same output with pool size.
I have big enough pool size and error messages are as follows
