From: Andre Noll Date: Fri, 23 Aug 2013 08:57:38 +0000 (+0200) Subject: overview.pdf: Fix overfull lines. X-Git-Tag: v0.5.0~3 X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=d72f1c098b91ab8991996698f396132591a2813e;p=paraslash.git overview.pdf: Fix overfull lines. The Ubuntu version of dia (which is used to create the public file on the web page) seems to behave differently than the self-compiled version used on my development box. This resulted in a rather strange looking pdf. Fix this by manually adjusting lines using the Ubuntu version. --- diff --git a/web/dia/overview.dia b/web/dia/overview.dia index d056dfd7..f9e01586 100644 --- a/web/dia/overview.dia +++ b/web/dia/overview.dia @@ -68,7 +68,7 @@ - + @@ -101,7 +101,7 @@ - + @@ -134,22 +134,24 @@ - + - #Incoming connections arrive via TCP at the dispatcher which creates a command -handler process for each connection. + #Incoming connections arrive via TCP at the dispatcher which creates a +command handler process for each connection. -After the connecting client has been authenticated, the command handler propagates -the incoming request either to the audio file selector (afs) or to the virtual streaming -system (vss).
