I'm editing a Makefile, and I came across this problem:
The first line is from php5/Makefile, and the second line is from www/apache22/Makefile. Why does the second line have a "?" after COMMENT?
Code:
COMMENT= PHP Scripting Language
COMMENT?= Version 2.2.x of Apache web server with ${WITH_MPM:L} MPM.
The first line is from php5/Makefile, and the second line is from www/apache22/Makefile. Why does the second line have a "?" after COMMENT?
