## -----------------------------------------------------------------------------
##
## Use "DEBUG=1" on the command line to cause librosie to log
## informational and error messages to stderr.
## 
## Use 'LUADEBUG=1' to include into the build a lua repl that can be
## accessed by passing '-D' to the rosie CLI as the first command line
## parameter.  This feature is needed for the white-box testing
## invoked by "make test".
##
## After compilation, the resulting files are placed in the "binaries"
## subdirectory.  
##
## ASAN_OPT may be set by a Makefile that calls this one.
##
## ROSIE_CLI may be set by a Makefile that calls this one.
