This information is implemented # in POD format, and can be viewed in a number of ways using # POD tools. Some viewing suggestions for this function's POD- # formatted information are: # # perldoc # pod2text -c # pod2text -c --code # pod2html # # However, the more important use for this information is that # it is parsed by clmgr to display the syntax for this file's # operation. The information in the "SYNOPSIS" section is used # for this purpose. This feature was originally implemented # using the man page information. However, in a code review it # was pointed out that this approach had to be changed because # customers do not have to install the man pages! Therefore, a # built-in dependency on man page information would break the # automatic help feature of clmgr. So the SYNPOSIS section must # be used instead. # # IMPORTANT: As a result of this, it is imperative that the # information in this SYNOPSIS be kept in sync # with the man page information, which is owned # by the IDD team. # # Inputs: None. # # Outputs: None. # # Returns: n/a (not intended to be invoked) # #============================================================================ function devDoc { : <<'=cut' >/dev/null 2>&1 =head1 NAME KLIB_HACMP_get_nova_attributes =head1 SYNOPSIS clmgr query nova [NovaLink] clmgr -v query nova =head1 DESCRIPTION Retrieves the data for NovaLink defined within the cluster configuration. =head1 ARGUMENTS 1.
