fpcmake is the Free Pascal makefile constructor program.
It reads a Makefile.fpc configuration file and converts it to a Makefile suitable for reading by GNU make to compile your projects. It is similar in functionality to GNU autoconf or Imake for making X projects.
fpcmake accepts filenames of makefile description files as its command line arguments. For each of these files it will create a Makefile in the same directory where the file is located, overwriting any other existing file.
If no options are given, it just attempts to read the file Makefile.fpc in the current directory and tries to construct a makefile from it. Any previously existing Makefile will be erased.
The format of the fpcmake configuration file is described in great detail in the appendices of the Programmers guide.
