This directory contains example scripts for creating XSB `.xwam` files
from Logtalk core files and Logtalk source files.

The following scripts are provided:

- `xsb_logtalk_xwam.sh`  
	Bash shell script for POSIX systems
- `xsb_logtalk_xwam.ps1`  
	PowerShell script for Windows systems

Both scripts create a `logtalk.xwam` file with the Logtalk compiler and
runtime and an optional `application.xwam` file for an application.

The `.xwam` files can be loaded by XSB using the `loader:load/1` predicate.
For example:

	| ?- loader:load(logtalk).

Usage
-----

Use `xsb_logtalk_xwam.sh -h` or `xsb_logtalk_xwam.ps1 -h` for a list and
description of the script options.

See the script usage examples in the `../SCRIPT.txt` file.

Known issues
------------

A ISO Prolog standard compliance bug in the handling of `initialization/1`
directives by XSB currently prevents passing a settings file to the script.
The same bug may also result also in predicate redefined warnings when
loading generated `application.xwam` files. This bug may be fixed in
recent XSB versions.
