############ the name of libtool to mklib. AutoRegen.sh checks for version

####### READ THIS:
####### THIS FILE IS BASED ON THE VERSION IN libtool 1.5.10.
####### The following changes have been made:
####### * this big bold header has been added
####### * fix obsolete constructs (ala autoupdate)
####### * the name of the generated tool is "mklib" instead of "libtool"
####### The last change is provided to avoid tab completion errors on the "lib"
####### prefix. AutoRegen.sh checks for version 1.5.10 of libtool so attempts
