extend -- produce an extended elevation from a .3d file SYNOPSIS
extend [--specfile configuration .espec file] input .3d file [output .3d file] Description Note: The extend program can also work on Compass .plt (as can aven and any other Survex program which reads .3d files). If no specfile is given, extend starts with the highest station marked as an entrance which has at least one underground survey leg attached to it. If there are no such stations, the highest deadend station in the survey (or the highest station if there are no deadends) is used. Extend puts the first station on the left, then folds each leg out individually to the right, breaking loops arbitrarily (usually at junctions). If the output filename is not specified, extend bases the output filename on the input filename, but ending "_extend.3d". For example, extend deep_pit.3d produces an extended elevation called deep_pit_extend.3d. This approach suffices for simple caves or sections of cave, but for more complicated situations human intervention is required. More com- plex sections of cave can be handled with a specfile giving directions to switch the direction of extension between left and right, to explicitly specify the start station, or to break the extension at particular stations or legs. The specfile is in a format similar to cavern's data format: ;This is a comment ; start the elevation at station entrance.a *start entrance.a ;this is a comment after a command ; start extending leftwards from station half-way-down.5 *eleft half-way-down.5 ; change direction of extension at further-down.8 *eswap further-down.8 ; extend right from further-down.junction, but only for ; the leg joining it to very-deep.1, other legs continuing ; as before *eright further-down.junction very-deep.1 ; break the survey at station side-loop.4 *break side-loop.4 ; break survey at station side-loop.junction but only ; for leg going to complex-loop.2 *break side-loop.junction complex-loop.2 This approach requires some trial and error, but gives useful results for many caves. The most complex systems would benefit from an interactive interface to select and view the breaks and switches of direction.

radio - console radio application SYNOPSIS
radio [ options ] DESCRIPTION
radio is a interactive, ncurses-bases console radio application. OPTIONS
-h print a short help text. -d enable debug output. -q quit after processing the cmd line options, don't enter interactive ncurses mode. Only useful together with other options for obvi- ous reasons ... -m mute radio. -f freq tune the specified radio frequency (and unmute the radio). -c dev specify radio device (default is /dev/radio). -s Do a scan for radio stations. -S Same as above + write a radio.fmmap with the signal for every frequency. You can get a graph for it with gnuplot (plot "radio.fmmap" w lin). -i Scan, write a initial ~/.radio file to stdout and quit. So you can create a config file where you only have to fill in the correct station names later this way: "radio -i > ~/.radio". See below for the config file syntax. CONFIGURATION
radio picks up station names and present stations from a config file. It can parse kradio (KDE radio app) config files, therefore it first tries the usual KDE config file location: ~/.kde/share/config/kradiorc. Failing that, radio tries ~/.radio (which makes things a bit easier for people who don't use kradio). The format looks like this: # KDE Config File [Buttons] 1=95800000 2=91400000 [Stations] 100600000=Hundert,6 95800000=Radio eins 102600000=Fritz 94300000=r.s.2 91400000=Berliner Rundfunk The [Buttons] section can have up to eight entries. That are the present stations, they get mapped to F1-F8. The [Stations] section maps frequencies to station names. The frequencies in both sections are specified in Hz. KEYS
X exit ESC,Q,E mute and exit. up/down inc/dec frequency pgup/pgdown next/previous station. This one uses the stations from the config file by default. When started with the -s option these keys will cycle througth the stations found during the scan. F1-F8, 1-8 preset buttons. Ctrl+L redraw screen. AUTHOR
