Originally, the Mizar system was implemented on an IBM-PC x86
compatibles under MS DOS. Now we distribute releases for
MS Windows, Intel-based Linux, Darwin/Mac OS X/macOS, Solaris and FreeBSD, and also Linux on PowerPC.
The whole Mizar system (including verifier) is coded in Pascal using
the Free Pascal compiler.
Andrzej Trybulec (1941-2013)
was the author of the Mizar Language,
he was also the head of the team implementing the verifier.

The contributed article is subject to a review and if needed
the authors must revise their file.
