Hey list,

I am experiencing two issues in compiling my document. The first is a
non-fatal warning during compilation of my book:

         ...
         (/usr/share/texmf/tex/context/base/s-abr-02.tex
         resolvers       > modules > 'abr-01' is loaded
         (/usr/share/texmf/tex/context/base/s-abr-01.tex))tr: invalid
         option -- '
         '
         Try 'tr --help' for more information.

         publications    > wrote a new auxiliary file \jobname.aux
         This is BibTeX, Version 0.99d (TeX Live 2012/Debian)
         The top-level auxiliary file: Handbook.aux
         The style file: cont-au.bst
         Database file #1: References/References.bib
         (/usr/share/texmf/tex/context/bib/bibl-apa.tex)
         ...

i'm not aware of a "tr" command so it's some kind of side effect i guess
