Re: Suggestion about best practice with .gpr files

[Per Sandberg <per.s.sandberg@bahnhof.se>]

Well that's the way I have been doing it for 20+ years with some small 
twists.
GPR_PROJECT_PATH points here:
!foolib/
!...|
!...+-- foolib.gpr
!...+-- src/
!........|foolib.ads
!...+-- lib/
!...+-- .obj/
!...+-- test/
!..........|
!..........+--foolib-test.gpr
!..........+-- .obj/
!..........+-- bin/
!..........+-- src/
!................|
!...............+-- foolib-tests-test_1.adb
!...............+-- foolib-tests-test_2.adb
!...............+-- foolib-tests-test_3.adb
!foxlib/
!application1/
!application2/

Then the experience i quite similar to what you get with an "eclipse 
workspace".
But with the capability to a lot of other structural exercises, such as 
having a baseline ReadOnly workspace and then using GPR_PROJECT_PATH to 
point first to a private workspace and then the baseline.
