The command "swig" is a software development tool used for generating code bindings between different programming languages. It simplifies the process of interfacing between a high-level language (such as Go) and a low-level language (such as C++).

In the given command:

• -go specifies that the target language for code generation is Go.
• -cgo enables the support for Go's cgo mechanism, which is used to call C code from Go.
• -intgosize 64 is an optional flag that indicates the size of the Go int type, specifying it as 64 bits.
• -c++ specifies that the input interface file is written in C++.

${path-to-swig_file-i} is a placeholder that should be replaced with the actual file path of the SWIG interface file (with the .i extension) you want to process.

Overall, this command is telling SWIG to process the specified interface file written in C++, generate Go code bindings using Go's cgo mechanism, and ensure that the int type in the generated Go code is 64 bits in size.
