man: Revise internal man page generation process.
For each section 8 man page, a .8_gen file is created from one of:
.8_main - Old-style man page - content used directly
.8_des and .8_end - Description and end section of a generated page
.8_pregen - Pre-generated page used if the generator fails
Other man sections are not generated and use the suffix .5_main or .7_main.
Developers should use 'make generate' to regenerate the .8_pregen files.

Each VG and LV has an allocation policy +which can be changed with vgchange/lvchange, or overriden on the +command line. +\fBnormal\fP applies common sense rules such as not placing parallel stripes +on the same PV. +\fBinherit\fP applies the VG policy to an LV. +\fBcontiguous\fP requires new PEs be placed adjacent to existing PEs. +\fBcling\fP places new PEs on the same PV as existing PEs in the same +stripe of the LV. +If there are sufficient PEs for an allocation, but normal does not +use them, \fBanywhere\fP will use them even if it reduces performance, +e.g. by placing two stripes on the same PV. +Optional positional PV args on the command line can also be used to limit +which PVs the command will use for allocation. +See \fBlvm\fP(8) for more information about allocation. +.ad b + +.HP +.ad l +\fB-A\fP|\fB--autobackup\fP \fBy\fP|\fBn\fP +.br +Specifies if metadata should be backed up automatically after a change. +Enabling this is strongly advised!
