>             Project: Fop
>          Issue Type: Bug
>          Components: fo/unqualified
>    Affects Versions: 1.1
>         Environment: windows 7 with cygwin
>            Reporter: Jürgen Krey
>            Priority: Minor
>
> When working with asciidoc / a2x and invoking fop, I found that there is 
> additional path conversion required for $fop_exec_args in the fop (bash) 
> script.
