# An example of embedding CEF browser in wxPython on Mac.

# IMPORTANT - importing CEF Python

# --------------------------------------------------------------

# The cefpython library must be the very first library imported.

# This is because CEF was compiled with the tcmalloc memory

# allocator which hooks globally and replaces the default

# malloc allocator. If memory was allocated using malloc and

# then freed using tcmalloc then this would result in random

# segmentation faults in an application. See Issue 155 which

# is to provide CEF builds on Mac with tcmalloc disabled:
