#load typically loads the latest project version that is marked
with a #release blessing. It is optional to have these convenience
methods on the class side.

If #load is missing you can implement it like this:

     load
	"self load"
	^self project latestVersion load

since typically one wants to quickly load the latest release version.

If you look in detail in ConfigurationOfScriptManager from 
squeaksource/MetacelloRepository then you will notice that
evaluating

 ConfigurationOfScriptManager project latestVersion

you will return version 1.1. although another version 1.2
exists. Guess why: the version 1.1 is marked as release by
setting the blessing to #release. 

     version11: spec 
	<version: '1.1' imports: #('1.0-baseline') >
	
	spec for: #common do: [
		spec blessing: #release.
                ...

while version 1.2 still is in development mode
 
     version12: spec 
	<version: '1.2' imports: #('1.0-baseline') >
	
	spec for: #common do: [
		spec blessing: #development.
                ...

Independent from all that you can always follow the usual 
pattern:

   (ConfigurationOfXXX project version: 'vv.vv') load

to load a specific version - where vv.vv is the version noted in 
the pragma (Metacello uses the pragmas and doesnt care about the 
method name). 

The other form you may have seem:

   ConfigurationOfXXX load

is just a timesaver to get the latest version. It may be missing
since most configs are written by hand since still more tools for
Metacello are missing.

-----------------------------------------------------------
And by the way:

Installer 
  ss 
  project: 'MetacelloRepository'; 
  install: 'ConfigurationOfExternalWebBrowser'. 

  (Smalltalk at: #ConfigurationOfExternalWebBrowser) load 

is now working in Squeak too. It is the same as:

  ((Smalltalk at: #ConfigurationOfExternalWebBrowser) project version: '1.1') load

-----------------------------------------------------------
If you require a ConfigurationOfAppleScript we can create 
one. Side note: a new book chapter on Metacello is in preparation
by Mariano, be patient or ask questions on the squeak/pharo list.

Have fun
