Use `make' loops instead of shell loops to install things. This fixes
the verbose output for `make -s install' and gives nicer output for
make install' and make -n install'. This method should be used more.

Install meteor and startslip. In fact, install all subdirectories
except CVS. This method should be used more so that SUBDIR lists don't
have to be changed so often (special cases could be handled by short
exclusion lists).
