5. INSTALLATION

Installing Logtalk is just a matter of uncompressing/unpacking the
distribution archive file for your operating system. You can install
Logtalk in any directory that you find convenient.

See the user manual for a description of the source files organization and 
for installing/using instructions (to read the user manual open the file 
manuals/index.html with a web browser).

In Unix and Unix-like systems you may want to define an environment variable 
named $LOGTALKHOME pointing to the Logtalk installation for use with your 
Prolog compilers. If you use a csh shell, add the following line to your 
.cshrc file:

	setenv LOGTALKHOME "/your/installation/directory/lgt2160"

If you use a bash shell, add the following lines to your .profile file:

	LOGTALKHOME="/your/installation/directory/lgt2160"
	export LOGTALKHOME


6. DOCUMENTATION

The reference and user manuals and the tutorial are provided in XHTML format 
and are contained in the manuals directory.

PDF versions of all documentation are also available as a separated download 
from the Logtalk web site. The PDF files include page numbers, index and a 
table of contents and are available for printing in both A4 and US Letter 
paper formats.

The file RELEASE_NOTES contains descriptions of the changes made in
Logtalk since the first public version. Read it carefully if you have
been using a previous Logtalk version.
