Subject: package_ipk.bbclass: make DESCRIPTION support newline
X-Git-Tag: lucaceresoli/bug-15201-perf-libtraceevent-missing~36718
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dff04de2de8bb159fd6912e29794eadd75d5d92a;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

package_ipk.bbclass: make DESCRIPTION support newline

The recipe's DESCRIPTION is wrapped automatically by textwrap, make it
support newline ("\n") to let the user can wrap it manually, e.g.:

DESCRIPTION = "Foo1\nFoo2"

In the past, it would be:
Foo1\nFoo2

Now:
Foo1
Foo2
