#!/bin/sh -e
# Concatanate package files in the installed package database
# File names are printed to stderr.
## SYNOPSIS:
## .Nm
## .Op Ar pkg
## .Op Ar file...
## DESCRIPTION:
## .Nm
## outputs the contents of the given package's database files to the standard
## output. The names of the files being printed will also be printed, but to
## stderr. Thus, you can pipe the contents of a file without worrying about
## mixing filenames into that file.
##
## If no package is specified,
## .Nm
## will assume that the package in the current directory is going to be printed.
##
## If no file is specified,
## .Nm
## will print the contents
## .Em build ,
## .Em depends ,
## .Em sources
## and
## .Em version
## files.
