/**
* \file cpl_string.h
*
* Various convenience functions for working with strings and string lists.
*
* A StringList is just an array of strings with the last pointer being
* NULL. An empty StringList may be either a NULL pointer, or a pointer to
* a pointer memory location with a NULL value.
*
* A common convention for StringLists is to use them to store name/value
* lists. In this case the contents are treated like a dictionary of
* name/value pairs. The actual data is formatted with each string having
* the format "<name>:<value>" (though "=" is also an acceptable separator).
* A number of the functions in the file operate on name/value style
* string lists (such as CSLSetNameValue(), and CSLFetchNameValue()).
*
* To some extent the CPLStringList C++ class can be used to abstract
* managing string lists a bit but still be able to return them from C
* functions.
