-case "$1" in ''|--help|-h) printf '\033[1;33m-> \033[musage: %s [file...]\n' "${0##*/}" ; exit 0 ; esac
+## SYNOPSIS:
+## .Nm
+## .Op Fl p Ar package
+## .Op Ar file...
 
-# Check if the package exists in a repository and error out here
-# if it does not. The error message from the package manager will
-# be displayed.
-cpt-search "${PKG:=${PWD##*/}}" >/dev/null
+## 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
