#!/bin/sh -ef
# Link a forked package's files to the other repository
## SYNOPSIS:
## .Nm
## .Op Fl p Ar package
## .Op Ar file...
## DESCRIPTION:
## .Nm
## symlinks files to the current package directory from a separate instance of
## the same package. If the
## .Fl p
## flag and a
## .Ar package
## is specified,
## .Nm
## will link files from the given package instead.
##
## .Nm
## creates symbolic links of package files using the realpath of the file, so it
## is therefore not suitable for using within a git repository, and should only
## be used internally.
## see: cpt-fork.1
