I used a Makefile for managing a large number of SSL certificates, private keys and trust stores. This was for an app that needed certs for IIS, Java, Apache and they all expect certificates to be presented in different formats. Using a Makefile allowed someone to quickly drop in new keys/certs and have all of the output formats built in a single command. Converting and packaging a single certificate requires one or more intermediate commands and Makefile is setup to directly handle this type of workflow.
