While working on this, Greg discovered a bug (issue #2154) that prevents a SideEffect() file from being used as input to another builder call; it makes the builder target not get build when run in paralle (e.g. -j2)... :-( So this patch comments out that section of Greg's section. This also contains my usual editing pass. In this case I changed some of the examples and added a bunch of text to try to help clarify some things that seemed important. I also added a closing paragraph warning that SideEffect() really shouldn't be used as an alternative to specifying multiple target files in a Builder call when a command builds more than one file that you care about. ........ r3246 | stevenknight | 2008-07-27 10:31:17 -0700 (Sun, 27 Jul 2008) | 2 lines Proofreading edits of the MergeFlags() section.
