# Defining the WUFFS_CONFIG__MODULE* macros are optional, but it lets users
|
|
# of Wuffs' .c file specify which parts of Wuffs to build. That file
|
|
# contains the entire Wuffs standard library, implementing a variety of
|
|
# codecs and file formats. Without this macro definition, an optimizing
|
|
# compiler or linker may very well discard Wuffs code for unused codecs,
|
|
# but listing the Wuffs modules we use makes that process explicit.
|
|
# Preprocessing means that such code simply isn't compiled.
