#
# See https://petsc.org/release/install/ for instructions on installing PETSc
#
# This is the top level makefile for compiling PETSc.
#   * make help - useful messages on functionality
#   * make all  - compile the PETSc libraries and utilities
#   * make check - runs a quick test that the libraries are built correctly and PETSc applications can run
#
#   * make install - for use with ./configure is run with the --prefix=directory option
#   * make test - runs a comprehensive test suite (requires gnumake)
#   * make docs - build the entire PETSc website of documentation (locally)
#   * a variety of rules that print library properties useful for building applications (use make help)
#   * a variety of rules for PETSc developers
#
# gmakefile - manages the compiling PETSc in parallel
# gmakefile.test - manages running the comprehensive test suite
#
# This makefile does not require GNUmake
