# packagens(n)

Construct an appropriate 'package ifneeded' command for a given package specification

## NAME

pkg::create - Construct an appropriate 'package ifneeded' command for a given package specification

## SYNOPSIS

**::pkg::create** *-name packageName* *-version packageVersion* ?*-load filespec*? ... ?*-source filespec*? ...

## DESCRIPTION

**::pkg::create** is a utility procedure that is part of the standard Tcl library.  It is used to create an appropriate **package ifneeded** command for a given package specification.  It can be used to construct a **pkgIndex.tcl** file for use with the **package** mechanism.

## OPTIONS

The parameters supported are:

- **-name** *packageName*

  This parameter specifies the name of the package.  It is required.

- **-version** *packageVersion*

  This parameter specifies the version of the package.  It is required.

- **-load** *filespec*

  This parameter specifies a binary library that must be loaded with the **load** command.  *filespec* is a list with two elements.  The first element is the name of the file to load.  The second, optional element is a list of commands supplied by loading that file.  If the list of procedures is empty or omitted, **::pkg::create** will set up the library for direct loading (see **pkg\_mkIndex**).  Any number of **-load** parameters may be specified.

- **-source** *filespec*

  This parameter is similar to the **-load** parameter, except that it specifies a Tcl library that must be loaded with the **source** command.  Any number of **-source** parameters may be specified.

At least one **-load** or **-source** parameter must be given.
