    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.
    
         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;
