 A macro to execute an expression and produce a report of any time spent importing packages and their
 dependencies. Any compilation time will be reported as a percentage, and how much of which was recompilation, if any.
 
-If a package's dependencies have already been imported either globally or by another dependency they will
-not appear under that package and the package will accurately report a faster load time than if it were to
-be loaded in isolation.

-!!! compat "Julia 1.9"
- Reporting of any compilation and recompilation time was added in Julia 1.9
+!!! note
+ During the load process a package sequentially imports all of its dependencies, not just its direct dependencies.

-!!! note
- During the load process a package sequentially imports where necessary all of its dependencies, not just
- its direct dependencies. That is also true for the dependencies themselves so nested importing will likely
- occur, but not always. Therefore the nesting shown in this output report is not equivalent to the dependency
- tree, but does indicate where import time has accumulated.
+!!! compat "Julia 1.8"
+ This macro requires at least Julia 1.8
