+#### Install Services
+Create and install a service
+1. `ds template list`  -- see what templates are available to install.

+output.hpp and output.cpp - simple output helpers.

+Defines ostreams:
+
+debug, info, warning, error.
+
+These ostreams can be used with C++23 print and println, e.g.
+std::println(debug, "funny variable: {}={}","my_var",my_var);
+
+Also defines a few helper functions:
+
+PrintDebug(const std::string& msg);     // equivalent to std::println(debug, msg);
+PrintInfo(const std::string& msg);      // equivalent to std::println(info, msg);
+PrintWarning(const std::string& msg);   // equivalent to std::println(warning, msg);
+PrintError(const std::string& msg);     // equivalent to std::println(error, msg);
+
+Output for these streams for each line is formatted as:
+[DBG] <message>
+[INF] <message>
+[WRN] <message>
+[ERR] <message>
+
+The output is coloured, and the tag is printed in grey.
+
+In addition, when not using any of the above, helper routines for coloring the output of cout and cerr are provided.
