</span>Under the line, that sounds like a complicated system to me, with the need for<br>
utils which are yet to be written.<br>
More, it will only work for those who adapt to that system. What about 3rd-<br>
party apps that want to develop again master branch of kdb? But use qmake? Or<br>
some other custom build system?<br>
<br>
What about using KProperty and KReport as testing ground for now for the<br>
approach you are proposing?<br></blockquote><div><br><div class="gmail_default" style="font-family:monospace,monospace;font-size:small;display:inline">+1 or look below<br></div><div class="gmail_default" style="font-family:monospace,monospace;font-size:small;display:inline"></div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

</span>For the start, for now, in current Calligra master I would like to propose to<br>
apply the BIC-day approach.<br>

The year+week number is a cross-repo too of course.

So a Stage&Flake-concentrated developer only has to pull kdb, kproperty &<br>
kreport on one day in the week, to always stay with a building master.<br>
<br>
Once there is a working alternative, which is understood and has working<br>
utils, we can switch to that any time.<br></blockquote><div><br><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
