# We can compress the embedded states with snappy before embedding them here.

|

# ATTENTION! This file is intentionally avoiding the Nim `/` operator for
|
||||
# constructing paths. The standard operator is relying the `DirSep` constant
|
||||
# which depends on the selected target OS (when doing cross-compilation), so
|
||||
# the compile-time manipulation of paths performed here will break (e.g. when
|
||||
# cross-compiling for Windows from Linux)
|
||||
#
|
||||
# Nim seems to need a more general solution for detecting the host OS during
|
||||
# compilation, so a host OS specific separator can be used when deriving paths
|
||||
# from `currentSourcePath`.
