### 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.
