# We write our own rules for yacc and lex below. We'd rather use automake,
# but automake makes it especially difficult for a number of reasons:
#
#  * < automake-1.12 generates .h files from .yy and .ypp files, but
#    >=automake-1.12 generates .hh and .hpp files respectively. There's no
#    good way of making a project that uses C++ yacc files compatible with
#    both versions of automake. Strong work automake developers.
#
#  * Since we're generating code from .l/.y files in a subdirectory (glcpp/)
#    we'd like the resulting generated code to also go in glcpp/ for purposes
#    of distribution. Automake gives no way to do this.
#
#  * Since we're building multiple yacc parsers into one library (and via one
#    Makefile) we have to use per-target YFLAGS. Using per-target YFLAGS causes
#    automake to name the resulting generated code as <library-name>_filename.c.
#    Frankly, that's ugly and we don't want a libglcpp_glcpp_parser.h file.

# In order to make build output print "LEX" and "YACC", we reproduce the
# automake variables below.
