Makefile Variables

[4exercise]

• Makefile variables are also known as: 'macros'

        PACKAGE = reduce2text
        SOURCE = file.html
        RESULT = file.txt
        VERSION = ` date +"%Y%m%d" `
        ARCHIVENAME = $(PACKAGE)-$(VERSION)
        ARCHIVE = $(ARCHIVENAME).tar.gz

• We can rewrite our 'make' statements using these variables.

        html2text: $(SOURCE)
                lynx -dump $(SOURCE) > $(RESULT)
