Subject: Instead of calling sys.exit when a ParseError occurs in the config
X-Git-Tag: v2.1.4~124
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=dee48ce8f7febb304cf4f56251ad7b3316ffaa67;p=portage.git

Instead of calling sys.exit when a ParseError occurs in the config
constructor, raise a ParseError and make emerge and portageq handle
the error. This way consumers of the portage api can handle the
ParseError rather than have their application exit. Thanks to lxnay
for reporting. (trunk r8884)
