OK.  I noticed you have use the leading / when using the full path to 
the install-info binary (i.e. /usr/bin/info-install vs. 
usr/bin/info-install) Other prototype install scripts do not use the 
leading slash.  Looking in the PKGBUILD man page, it is not specified 
which is right.  So, does this matter and if so, which is actually correct?
