+# Errtags
+
+## Idea
+The normal way to do error reporting is redefining your build-system to vim.
+Thats disguasting.
+
+The right way should be to hook into the actual build system.
+
+## Process
+Make is our friend, because its hackable.
+
+ token := genrate-session-token()
+ foreach t in $tools do
+ $t($token)
+ done
+
+The session token is a number used to differentiate between compiles.
+
+Every tool is wrapped, so that it emits its output to both normally and piped into errtags.
+
+Errtags is responsible for grepping error messages and storing them in a csv-like file.
+
+The csv is passed to vim so it can display the errors.
