+NAME
+ /precompiled/string_buffer - incremental string buffer
+
+DESCRIPTION
+ string_buffer implements a fast way to build strings by appending
+ strings or chars to the end of the buffer.
+
+BUGS
+ This object is not thread-safe, if several threads access the same
+ buffer they have to protect the accesses with mutex locks.
+
+============================================================================
+NAME
+ create - initielize the buffer
+
+SYNTAX
+ #include <string.h>
+
+ void string_buffer->create();
+ or
+ object clone(String_buffer);
+
+DESCRIPTION
+ This function initializes the string buffer. You can call this
+ function to clear the contents of the buffer once it has been
+ used.
+
+============================================================================
+NAME
+ append - append a string to the buffer
+
+SYNTAX
+ #include <string.h>
+
+ void string_buffer->append(string s);
+
+DESCRIPTION
+ This function appends the string s to the end of the buffer.
+
+============================================================================
+NAME
+ get_buffer - get the contents of the buffer as a string.
+
+SYNTAX
+ #include <string.h>
+
+ mixed string_buffer->get_buffer();
+ or
+ (string)string_buffer;
+
+DESCRIPTION
+ This function retreives the content of the buffer. Note that it does
+ not clear the contents of the buffer. You have to do that yourself
+ with create().
+
