<P>
Jambase is a base set of Jam/MR rules which
provide roughly make(1)-like functionality for
<a href="Jam.html"><b>jam</b></A>, the Jam/MR executable program.
This document, which started out as the Jambase(5) man page,
is a reference guide to the
<A href="#RULES">rules</A>,
<A href="#PSEUDOTARGETS">pseudotargets</A>,
and <A href="#VARS">variables</A>
defined in Jambase for use in Jamfiles.

<A NAME="PSEUDOTARGETS">
<H3>
Jambase Pseudotargets
</H3>
</A>
<P>
There are two kinds of Jam targets: file targets and pseudotargets.
File targets are objects that can be found in the filesystem.
Pseudotargets are symbolic, and usually represent other targets.
Most Jambase rules that define file targets also define pseudotargets
which are dependent on types of file targets. The Jambase pseudotargets
are:
<CENTER>
<TABLE CELLPADDING=5%>
<TR><TD>exe
<TD>Executables linked by the Main or MainFromObjects rules
<TR><TD>lib
<TD>Libraries created by the Library or LibraryFromObjects rules
<TR><TD>obj
<TD>Compiled objects used to create Main or Library targets
<TR><TD>dirs
<TD>Directories where target files are written
<TR><TD>file
<TD>Files copied by File and Bulk rules
<TR><TD>shell
<TD>Files copied by Shell rule
<TR><TD>clean
<TD>Removal of built targets (except files copied by Install* rules)
<TR><TD>install
<TD>Files copied by Install* rules
<TR><TD>uninstall
<TD>Removal of targets copied by Install* rules
</TABLE>
</CENTER>
<P>
In addition, Jambase makes the <b>jam</b> default target "all"
depend on "exe", "lib", "obj", "files", and "shell".
<P>
<HR>
<A NAME="VARS">
<H3>

<P>
Most of the following variables have default values for
each platform; refer to the Jambase file to see what those
defaults are.
<P>
ALL_LOCATE_TARGET
<BLOCKQUOTE>
Alternative location of built targets. By default,
Jambase rules locate built targets in the source
tree. By setting $(ALL_LOCATE_TARGET)
in Jamrules, you can cause <b>jam</b>
to write built targets to a location outside
the source tree.
</BLOCKQUOTE>
AR
<BLOCKQUOTE>
The archive command used to update Library
and LibraryFromObjects targets.
</BLOCKQUOTE>

does not depend on these libraries.
</BLOCKQUOTE>

created whole.
</BLOCKQUOTE>
OPTIM
