2. All of the entities which the symbol/* pattern matches are
directories. You could use symbol/*/* instead, but that would match
symbol/CVS/* and symbol/*/CVS.
3. The install-sh script doesn't support installing multiple files in
a single command; you need to use a "for" loop or similar.
If you don't want to use "tar" (which has problems, e.g. preserving
ownership and permissions on the copied files), use:
find symbol -path '*/CVS' -prune -o -type d -print | while read dir ; do \
$(MKDIR) $(ETC)/"$$dir" ; \
done
find symbol -path '*/CVS' -prune -o -type f -print | while read file ; do \
$(INSTALL_DATA) "$$file" $(ETC)/"$$file" ; \
done
