# This utility concatenates several files into one. On Unix-like systems

# it is equivalent to:
|

|
|
# cat file1 file2 file3 ...files... > target
|

# The reason for writing a seperate utility is that 'cat' is not available
|
||
|
|
# on all supported build platforms, but Python is, and hence this provides
|
||
|
|
# us with an easy and uniform way of doing this on all platforms.
