.construction: <<<OPTIONAL>>> PURPOSE: Describe the type of language(s) used to create this program and the methods used to build the final executable. If possible, include the compiler version(s) and possibly important options, such as optimization. FORMAT: Free form; see .description for more information. EXAMPLE: SAS/C++ 6.5 with full optimization. EXAMPLE: AdaEd. EXAMPLE: Fortran with self-made compiler. EXAMPLE: AMOS NOTES: This is usually closely related to the .exectype field but differs from it in that the .exectype might be "Compiled C" but the compiler used was "RottenC 0.97"
