+
+Checking the PETSc version
+--------------------------
+The PETSc version
+is defined in ``$PETSC_DIR/include/petscversion.h`` with the three macros
+``PETSC_VERSION_MAJOR``, ``PETSC_VERSION_MINOR``, and ``PETSC_VERSION_SUBMINOR``.
+
+The shell commands ``make getversion`` or ``$PETSC_DIR/lib/petsc/bin/petscversion`` prints out the PETSc version.
+The command 
+
+   .. code-block:: console
+
+      $ $PETSC_DIR/lib/petsc/bin/petscversion <eq,gt,lt,ge,le> major.minor<.subminor>
+
+allows one to add tests to make files, CMake files, configure scripts etc, to ensure the PETSc version is compatible with your applications. For example,
+
+   .. code-block:: console
+
+      $ $PETSC_DIR/lib/petsc/bin/petscversion eq 3.22
+
+returns 1 if the PETSc version is 3.22 (any subminor version is allowed). While 
+
+   .. code-block:: console
+
+      $ $PETSC_DIR/lib/petsc/bin/petscversion ge 3.21
+
+returns 1 if the PETSc version is 3.21 or higher.
+
+
+Though we try to avoid making changes to the PETSc API, they are inevitable; thus we
+provide tools to help manage one's application to be robust to such changes.
+
+During configure/make time
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The command
+
+.. code-block:: console
+
+   $ $PETSC_DIR/lib/petsc/bin/petscversion eq xxx.yyy[.zzz]
+
+prints out 1 if the PETSc version matches ``xxx.yyy[.zzz]`` and 0 otherwise. The command works in a similar
+way for ``lt``, ``le``, ``gt``, and ``ge``. This allows your application configure script, or ``makefile`` or ``CMake`` file
+to check if the PETSc version is compatible with application even before beginning to compile your code.
+
+
+During compile time
+~~~~~~~~~~~~~~~~~~~
+
+The CPP macros
+
+- ``PETSC_VERSION_EQ(MAJOR,MINOR,SUBMINOR)``
+- ``PETSC_VERSION_LT(MAJOR,MINOR,SUBMINOR)``
+- ``PETSC_VERSION_LE(MAJOR,MINOR,SUBMINOR)``
+- ``PETSC_VERSION_GT(MAJOR,MINOR,SUBMINOR)``
+- ``PETSC_VERSION_GE(MAJOR,MINOR,SUBMINOR)``
+
+may be used in the source code to choose different code paths or error out depending on the PETSc version.
+
+At Runtime
+~~~~~~~~~~
+
+
+The command
+
+.. code-block:: C
+
+   char  version(lengthofversion);
+   PetscErrorCode PetscGetVersion(char version[], size_t lengthofversion)
+
+gives access to the version at runtime.
