# NAME
|
|
# pkg_path -- canonicalize directories into "package paths"
|
|
#
|
|
# SYNOPSIS
|
|
# pkg_path [-s pkgsrcdir] dir ...
|
|
#
|
|
# OPTIONS
|
|
# The following command line arguments are supported.
|
|
#
|
|
# -s pkgsrcdir Use the specified directory as the path to the
|
|
# pkgsrc directory tree. By default, this is the
|
|
# value stored in the PKGSRCDIR environment variable.
|
|
#
|
|
# DESCRIPTION
|
|
# pkg_path canonicalizes the specified directories into package
|
|
# paths that are relative to the pkgsrc directory tree, and prints
|
|
# each of them to standard output on a new line. The specified
|
|
# directories are taken to be relative to the current directory.
|
|
# Directories that are not valid package directories or are not
|
|
# found are skipped during processing.
|
|
#
|
|
# ENVIRONMENT
|
|
# PKGSRCDIR This is the location of the pkgsrc directory tree,
|
|
# which defaults to "/usr/pkgsrc".
|
|
