# the gyp file the "base directory" within the per-.gyp-file
# NinjaWriter code.
#
# All paths as written into the .ninja files are relative to the build
# directory. Call these paths "ninja paths".

# functions:
#
# - GypPathToNinja translates a gyp path (i.e. relative to the .gyp file)
# into the equivalent ninja path.
#
# - GypPathToUniqueOutput translates a gyp path into a ninja path to write
# an output file; the result can be namespaced such that it is unique
# to the input file name as well as the output target name.
