# PGAC_CLASS_STRING |
|

# ----------------- |
|
||||||
# Look for class `string'. First look for the <string> header. If this |
|
||||||
# is found a <string> header then it's probably safe to assume that |
|
||||||
# class string exists. If not, check to make sure that <string.h> |
|
||||||
# defines class `string'. |
