bt101 has asked for the
wisdom of the Perl Monks concerning the following question:
I normally write one-file scripts. However I have written a rather extensive set of routines and I would like to re-use the code for several programs. I gather the way to do this is to split up the code and put it into packages. However my mind is boggling on how several things should work. One example is...let's say your original one-file program writes logs using log4perl. In that case you simply initialize the log and then call routines to write to that log from anywhere in your program. How does/should this work when you have split the code into packages? If you initialize log4perl in the main code, how to all of the package routines write to the log file? It is so simple with C where multiple files are just linked into one flat program. I'm fundamentally missing something.
