[logback-dev] While you are working on FileAppenders... was: Question about a custom binary file appender.

[Ceki Gulcu]

Hi Joern,

Plese enter a bug report with as much information as you can about the
code you'd like to see changed.  In principle, very little code is
involved in actually writing to the file so the task would seem rather
easy. However, WriterAppender on which FileAppender and
RollingFileAppender are built upon uses a Writer to write whatever it
is that needs to be written. Unfortunately, a Writer knows how to
writes String or chars, but not bytes.

Nevertheless, I think it's feasible with some work...
