## another Java compiler doesn't matter.

## srcdir shall contain absolute path to package directory.

## objdir shall contain absolute path to this build directory.

## bootclasspath shall contain jar or zip file required to
## boot Javac. An example where this variable is used is 
## jikes. Note, this variable can be plain empty.

## environment variable $JAVACFLAGS - see below.

## Regardless what has been configured, a user should always
## be able to  override  without  the need to reconfigure or
## change this file. Therefore we check variable $JAVACFLAGS.
## In almost all cases the precomputed flags are just ok but
## some  additional  flags are needed. To support this in an
## easy way, we check for the very first value. If this val-
## ue is 
## '+'  -> append content of JAVACFLAGS to precomputed flags
## '-'  -> prepend content    -*-
## '='  -> do not use precomputed flags
## If none of these characters are given, the behaviour will
## be the same as if "=" would have been given.
