I've had quite an odyssey to come to my present understanding of the
SqueakMap package loader. The way I now understand it is as follows:<br>
<ol>
<li> SqueakMap packages can be seen in the middle-left list pane
of SqueakMap Package Loader. The context menu in this pane
filters which packages to show. The bottom-left list pane
appears to be another selection filter. I deselect all to avoid
surprises. <br>
</li>
<li>Details about the selected package are shown in the right
pane.<br>
</li>
<li>A selected SqueakMap package can contain releases. Available
releases are listed below the package name in the SqueakMap
Package Loader. A new release can be created though the
context menu of a selected package: "Create new Release". (There
are more alternatives that I haven't investigated.)</li>
<li>Details about a selected release are shown in the right pane.
One detail shown for every release is called "<i>Download:
<URL></i>". The URL identifies a file that specifies the
installation. I have seen an .st file that will be executed as a
doIt, and a .sar file that contains 3 .st files: a preamble, an
installation file, and a postscript. <br>
</li>
<li>One command available for a selected release is "Edit
release". This opens a "fill-in-the-form" called a Release
browser. Most fields are explained by hovering the mouse above
the field. The exception is the bottom field; it can contain a
script for the installation. I haven't found a good explanation
for this script anywhere. I first thought it wasn't important
because most releases shown in the package loader leave the
script empty. I now see the field as an input field. Fill it
with executable Squeak code and save it. It will then be
transformed into file, stored somewhere, and become retrievable
through the URL in the "<i>Download: <URL></i><i></i>".
This scheme seems extremely powerful but only for the person who
knows the various installation mechanisms. <br>
</li>
</ol>
<blockquote>
<ul>
<li>Chris pointed me to a script statement for downloading a
SqueakSource package known by its URL. e.g., <br>
(Installer repository:
'<a class="moz-txt-link-freetext" href="http://www.squeaksource.com/DCI">http://www.squeaksource.com/DCI</a>') install:
'BBAllInOne-TRee.18' .<br>
this happens to be an Monticello configuration file,
BBAllInOne-TRee.18.mcm.</li>
<li>Another statement I have seen is<br>
SMSqueakMap default installPackageNamed:
'<name>' version: '<version>' <br>
I couldn't make it work for me, but suspect that the package
shall be stored as a versioned file in SqueakMap itself. <br>
</li>
</ul>
</blockquote>
This is as far as I've got. I hope somebody will correct the
explanation where it is wrong so that other people may make use of
it. I would have been spared considerable time and frustration if I
had seen it a couple of weeks ago.<br>
<br>

<pre wrap="">
They /all/ have a Download URL. What varies is what type of file is
found at that url. When you entered the script above and clicked
"Save" in the Release Editor browser, it saved it as a ".st" file on
the SM server, with the "Download URL" field pointing to it.
SqueakMap will still interpret .mcz, .sar, as well as .st files and
"do the right thing" for each type.

<pre wrap="">
Curious, does it handle .mcm directly nowadays?
</pre>
</blockquote>
<pre wrap="">
It appears not but could be done by adding new subclass of SMSimpleInstaller.
