# splitDllBegin(part_list [, config [, exclusive_config_list]])
#
# Splits the DLL target to several separate parts according to part_list where
# each part is a suffix appended to the original DLL name and the number of
# parts determines the number of resulting DLLs.
#
# An optional config argument specifies the CONFIG scope in which the split
# should occur. In this case, exclusive_config_list may be used to specify
# a |-separated list of mutually exclusive scopes so that the last one added
# will be actually in effect.
#
# This function only begins the split process. In order to make it work,
# the splitDllPart function must be used to define the sources for each part
# and then splitDllEnd is called to finalize the split process. See individual
# function descriptions for more details.
