Apparently BitcodeReader.h is only in lib/Bitcode/Reader/ but not in
include, so a make install does not install it.

Is it supposed to be accessible from applications? How exactly? I feel that
some install rule is missing; after a sudo make install, 
  grep -rn BitcodeReader /usr/local/include/llvm/
don't find any occurrence! Is this a bug or a misunderstanding of mine?

Can I assume the bytecode interface is obsolete and to be replaced by bitcode?

BTW, my hoobby project is an hypertextual programming language experiment
with only a Web interface (no source files). So I want to store every
procuced llbm Module in a MySQL database.
