Subject: Improved doc and samples default target.
X-Git-Tag: V2.16~97
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=c9e9679a06afd86fe8caeb32177c11736b98a974;p=cc65

Improved doc and samples default target.

The 'all' target deliberately doesn't build the doc nor the samples. But that doesn't mean that the Makefiles in the 'doc' and 'samples' directories must default to the (empty) 'all' target.
