The package reprinted to the http://www.cnblogs.com/rchen/archive/2005/09/07/231885.htmlDelphi is divided into four types:
1. runtime package
2. design package
3. runtime and design-time packages
4. Neither runtime nor design-time package

Generally, the runtime package is used. Three files are required during package distribution:

. BPL: the Library file of the package, which is equivalent to DLL.
. DCP: the package's symbolic file (metadata ).
. DCU: compiled unit file

The installation method is as follows:

Copy. BPL and. DCP to the installation directory \ projects \ BPL in Delphi,
Copy. DCU to the installation directory \ Lib of Delphi,
Then you can install the package in the menu.
