<h1>Documentation</h1>
<b>PETSc</b> is a
sophisticated package and fully understanding its usage
requires time. However, application programmers can easily begin to
use <b>PETSc</b> from a high level and then gradually learn more
details according to their needs. Users should read the users
manual before attempting to do any serious coding with <b>PETSc</b>!
