# ----

# Wuffs ships as a "single file C library" or "header file library" as per
# https://github.com/nothings/stb/blob/master/docs/stb_howto.txt
#
# To use that single file as a "foo.c"-like implementation, instead of a
# "foo.h"-like header, #define WUFFS_IMPLEMENTATION before #include'ing or
# compiling it.

"WUFFS_IMPLEMENTATION",
# Continuing to copy/paste:
#
# ----
#
# Defining the WUFFS_CONFIG__MODULE* macros are optional, but it lets users
# of Wuffs' .c file whitelist 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.
#
# ----
#
# For Skia, we're only interested in particular image codes (e.g. GIF) and
# their dependencies (e.g. BASE, LZW).
