Welcome
jmartin,
I have a few to questions pose in response first:-
- Is this homework/assignment? There are specific forums for these.
- What have you tried so far?
- What output/errors do you get?
- What OS and version are you using?
- What are your preferred tools? (C, shell, perl, awk, etc.)
- What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly,
What have you tried so far?
There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.
We're all here to learn and getting the relevant information will help us all.

NAME
lib - manipulate @INC at compile time
SYNOPSIS
use lib LIST;
no lib LIST;
DESCRIPTION
This is a small simple module which simplifies the manipulation of @INC at compile time.
It is typically used to add extra directories to perl's search path so that later "use" or "require" statements will find modules which are
not located on perl's default search path.
Adding directories to @INC
The parameters to "use lib" are added to the start of the perl search path. Saying
use lib LIST;
is almost the same as saying
BEGIN { unshift(@INC, LIST) }
For each directory in LIST (called $dir here) the lib module also checks to see if a directory called $dir/$archname/auto exists. If so
the $dir/$archname directory is assumed to be a corresponding architecture specific directory and is added to @INC in front of $dir.
lib.pm also checks if directories called $dir/$version and $dir/$version/$archname exist and adds these directories to @INC.
The current value of $archname can be found with this command:
perl -V:archname
The corresponding command to get the current value of $version is:
perl -V:version
To avoid memory leaks, all trailing duplicate entries in @INC are removed.
Deleting directories from @INC
You should normally only add directories to @INC. If you need to delete directories from @INC take care to only delete those which you
added yourself or which you are certain are not needed by other modules in your script. Other modules may have added directories which
they need for correct operation.
The "no lib" statement deletes all instances of each named directory from @INC.
For each directory in LIST (called $dir here) the lib module also checks to see if a directory called $dir/$archname/auto exists. If so
the $dir/$archname directory is assumed to be a corresponding architecture specific directory and is also deleted from @INC.
Restoring original @INC
When the lib module is first loaded it records the current value of @INC in an array @lib::ORIG_INC. To restore @INC to that value you can
say
@INC = @lib::ORIG_INC;
CAVEATS
In order to keep lib.pm small and simple, it only works with Unix filepaths. This doesn't mean it only works on Unix, but non-Unix users
must first translate their file paths to Unix conventions.
# VMS users wanting to put [.stuff.moo] into
# their @INC would write
use lib 'stuff/moo';
NOTES
In the future, this module will likely use File::Spec for determining paths, as it does now for Mac OS (where Unix-style or Mac-style paths
work, and Unix-style paths are converted properly to Mac-style paths before being added to @INC).
If you try to add a file to @INC as follows:
use lib 'this_is_a_file.txt';
"lib" will warn about this. The sole exceptions are files with the ".par" extension which are intended to be used as libraries.
SEE ALSO
FindBin - optional module which deals with paths relative to the source file.
PAR - optional module which can treat ".par" files as Perl libraries.
