+<h2>DESCRIPTION</h2>
+
+<em>v.external.all</em> creates
+(using <em><a href="v.external.html">v.external</a></em>) in the
+current mapset new pseudo-vector maps for all OGR layers from given
+OGR datasource (<b>dsn</b> option).
+
+<h2>EXAMPLES</h2>
+
+<h3>PostGIS</h3>
+
+List available feature tables in given PostGIS database
+
+<div class="code"><pre>
+v.external.all -l dsn=PG:dbname=pgis_nc
+
+PostGIS database <pgis_nc> contains 55 feature table(s):
+boundary_county
+boundary_municp
+bridges
+busroute1
+busroute11
+busroute6
+busroute_a
+busroutesall
+busstopsall
+censusblk_swwake
+census_wake2000
+...
+</pre></div>
+
+Create links (ie. pseudo-vector maps) in the current mapset for all
+PostGIS feature tables
+
+<div class="code"><pre>
+v.external.all dsn=PG:dbname=pgis_nc
+</pre></div>
+
+<h3>Esri Shapefile</h3>
+
+<div class="code"><pre>
+v.external.all -l dsn=~/geodata/ncshape/
+Data source </home/martin/geodata/ncshape/> (format 'ESRI Shapefile')
+contains 44 layers:
+poi_names_wake
