Re: [libredwg] Undefined References

[Dave Coventry]

With regard to this, the libredwg library needs to be explicitly
compiled in by appending "-lredwg" onto the end of the command string.

gcc -Wall -g -pedantic -std=gnu99 dwgout.c -o dwgout -lredwg

Perhaps this should be incorporated into the README?
