116 The actual characteristics of each type are defined by the semantics of the
117 programming language and the specific language implementation that was used
118 to compile the target program. See the language-specific notes in the
119 documentation of each method.
120 
121 SBType instances can be obtained by a variety of methods.
122 `SBTarget.FindFirstType` and `SBModule.FindFirstType` can be used to create
123 `SBType` representations of types in executables/libraries with debug
124 information. For some languages such as C, C++ and Objective-C it is possible
125 to create new types by evaluating expressions that define a new type.
126 
127 Note that most `SBType` properties are computed independently of any runtime
128 information so for dynamic languages the functionality can be very limited.
129 `SBValue` can be used to represent runtime values which then can be more
130 accurately queried for certain information such as byte size.
131 
132 
133 SBType supports the eq/ne operator. For example,::
134 
135     //main.cpp:
136 
137     class Task {
138     public:
139         int id;
