-
- &SCons; construction environments have a &MergeFlags; method
- that merges a dictionary of values into the construction environment.
- &MergeFlags; treats each value in the dictionary
- as a list of options such as one might pass to a command
- (such as a compiler or linker).
- &MergeFlags; will not duplicate an option
- if it already exists in the construction environment variable.
-
- </para>
-
- <para>
-
- &MergeFlags; tries to be intelligent about merging options.
- When merging options to any variable
- whose name ends in <varname>PATH</varname>,
- &MergeFlags; keeps the leftmost occurrence of the option,
- because in typical lists of directory paths,
- the first occurrence "wins."
- When merging options to any other variable name,
- &MergeFlags; keeps the rightmost occurrence of the option,
- because in a list of typical command-line options,
- the last occurrence "wins."

- Note that the default value for &cv-link-CCFLAGS;

- is an internal &SCons; object
- which automatically converts

-
- Note that the default value for &cv-link-CPPPATH;
- <!--
- [TODO: for when we make CLVar public]
- is a Python list, not a <varname>CLVar</varname>,
- -->
- is a normal Python list,
- so we must specify its values as a list
- in the dictionary we pass to the &MergeFlags; function.
-
- </para>
-
- <para>
-
- If &MergeFlags; is passed anything other than a dictionary,
- it calls the &ParseFlags; method to convert it into a dictionary.

-
- In the combined example above,
- &ParseFlags; has sorted the options into their corresponding variables
- and returned a dictionary for &MergeFlags; to apply
- to the construction variables
- in the specified construction environment.
