Devel::TraceUse - show the modules your program loads, recursively
An apparently simple program may load a lot of modules. That's useful, but sometimes you may wonder exactly which part of your program loads which module.
Devel::TraceUse can analyze a program to see which part used which module.
I recommend using it from the command line:
$ B<perl -d:TraceUse your_program.pl>
This will display a tree of the modules ultimately used to run your program. (It also runs your program with only a little startup cost all the way through to the end.)
Modules used from your_program.pl: Test::MockObject::Extends, line 6 (0.000514) Test::MockObject, line 6 (0.000408) Scalar::Util, line 9 (0.000521) List::Util, line 12 (0.000393) XSLoader, line 24 (0.000396) UNIVERSAL::isa, line 10 (0.000436) UNIVERSAL, line 8 (0.000247) UNIVERSAL::can, line 11 (0.000428) Test::Builder, line 13 (0.000413) Devel::Peek, line 8 (0.000693)
