.IX Header "DESCRIPTION"
Ace::Browser::SiteDefs evaluates an AceBrowser configuration file and
returns a configuration object (\*(L"config object\*(R" for short).  A config
object is a bag of dynamically-generated methods, derived from the
scalar variables, arrays, hashes and subroutines in the configuration
file.
.PP
The config object methods are a canonicalized form of the
configuration file variables, in which the first character of the
method is uppercase, and subsequent characters are lower case.  For
example, if the configuration variable was \f(CW$ROOT\fR, the method will be
\&\f(CW$config_object\fR\->Root.
.SS "Working with Configuration Objects"
.IX Subsection "Working with Configuration Objects"
To fetch a configuration object, use the Ace::Browser::AceSubs
\&\fBConfiguration()\fR function.  This will return a configuration object for 
the current database:
.PP
.Vb 1
\&  $config_object = Configuration();
.Ve

Thereafter, it's just a matter of making the proper method calls.
