-=head1 NAME
-
-File::Spec::OS2 - methods for OS/2 file specs
-
-=head1 SYNOPSIS
-
- require File::Spec::OS2; # Done internally by File::Spec if needed
-
-=head1 DESCRIPTION
-
-See L<File::Spec> and L<File::Spec::Unix>. This package overrides the
-implementation of these methods, not the semantics.
-
-Amongst the changes made for OS/2 are...
-
-=over 4
-
-=item tmpdir
-
-Modifies the list of places temp directory information is looked for.
-
- $ENV{TMPDIR}
- $ENV{TEMP}
- $ENV{TMP}
- /tmp
- /
-
-=item splitpath
-
-Volumes can be drive letters or UNC sharenames (\\server\share).
