This is not a module, but an independant binary used by hyp71_mgr.
It is a slightly modified version by Alexandre Nercessian of the widely used USGS location program.
Modifications allow higher number of stations, altitudes to be taken into account,
earthquakes above sea level as well as stations below sea level.
Jean-Marie SAUREL 07/15/2011

Written by Ruben Luis of CVARG. Produces a fancy email with HTML using
embedded images and a google map. Is triggered by a TYPE_HYP2000ARC
message. This is in the reporting section of the source
Ruben Luis 07/07/2011

Written by Jim Luetgert for taking netquakes mseed data and injecting it
into a ring, winston wave server, gif files and peak ground motion calcuations.
Moved from Contrib/Menlo to data_sources in EW7.5
Moved by Paul Friberg 07/07/2011

This is a module to do for NonLinLoc what hyp2000_mgr does for hypoinverse. It
basically runs NonLinLoc and converts the input and output so that it matches
what hyp2000 does so that downstream programs can get a new earthquake solution.
This uses Anthony Lomax's NonLinLoc locator program found here:
The nll_mgr was contributed by INGV but written by Anthony. Formerly this was in
the Contrib bundle, but it is in use in a few places as a production module.
NOTE that we are also including NonLinLoc with each EW release as a convenience,
but if you need the latest, go to Anthony's web site link above.

A Java 1.6 GUI that receives HYP2000ARC messages from import and creates alert
emails and SMS (sms using clickatel interface) with information about the
event. In addition to the origin info, it sends emails with a google map of
the location and a .png display of the waveforms that had picks.

This module sends regularly trig2k messages in order for a listening trig2disk
to produce continuous data archiving. It can replace the contrecord Perl and modules
of GlowWorm package (used until v6.3).
Based on carlsubtrig module.
Tested under Linux CentOS.
Jean-Marie Saurel 03/12/2010

This module converts trig2k messages into hyp2000_arc messages.
Only the stations that has been trigged are send in the output.
P arrival time is the trigger time for each station, and the weight is 4.
Tested under Linux CentOS.
Jean-Marie Saurel 03/12/2010

This module is contributed from Richard Luckette and Doug Scott of the BGS
and it takes an HYPO2000ARC message and converts it to SEISAN event format.
Paul Friberg 12/07/2010

This module allows to use Hypo71 at the end of the megamodule instead of hyp2000.
The input/output is the same as hyp2000_mgr module.
It allors also to compute and integrate local magnitude using standalone mode
of localmag.
Tested under several Linux flavours.
Jean-Marie Saurel 10/12/2010

This module takes data from one or more waveservers, computes and processes
their spectra; results can be written either to a file or a ring.  Processing
includes tapering, smoothing, filtering, and peak identification.  Data
acqusition can be initiated from the config file or from a message read from a
specified ring (see 'compute_spectra').
Scott Hunter 04/26/2011

This module posts a message that, when read by ewspectra, begins processing data
starting at the specified date/time.  (Deprecated w/ the creation of
Scott Hunter 04/26/2011

This module is a sniffwave for spectra messages, as written by ewspectra.  Results
can be directed to stdout or to a different file for each message "sniffed", in
a specified directory.
Scott Hunter 04/26/2011

This module monitors a ring for TRACEBUF2X messages and generates an alarm message
when a SCNL-specific threshold is exceeded.
Scott Hunter 04/26/2011

This module puts an ACTIVATE_MODULE message in the specified ring, the body of
which starts with the module ID of the specified target module, followed by the
remaining command-line arguments.
Scott Hunter 05/05/2011

This module, upon reading an ACTIVATE_MODULE message in the specified ring,
executes a sequence of scripts (making substitutions w/ supplied arguments),
and reports the final return code in a message to the specified ring.
Scott Hunter 05/18/2011

This module monitors a ring for ACTIVATE_MODULE or alarm messages; generates email
and posts a message to a ring for an instance of activated_scripts.
Scott Hunter 05/20/2011

This module monitors a ring for TRACEBUF2 messages, assumed to be from
sensors on different floors of a building.  The sum of the forces for the floors
is computed for each sample time and, if it exceeds a specified threshold, an
alarm message is written to an output ring.
Scott Hunter 06/08/2011

This module is a multi-threaded version of sendfileII that runs as an Earthworm module,
meaning it sends heartbeats to statmgr, and restarts like other well-behaved EW modules.
Running sendfilemt is equivalent to running multiple copies of sendfileII, but
only one only one configuration file is needed, and sendfilemt needs to be mentioned only
once in the startstop.d and statmgr.d files.  The module was tested on Solaris and Windows,
Since sendfilemt uses the standard multithread Earthworm functions, it will probably run
ok on other operating systems too, if the appropriate makefiles are written.
Will Kohler 7/24/2011

Adsendxs is a rewrite the old adsend module that works with newer model DAQ hardware and
GPS receivers. Here are some features of adsendxs:
- Runs on National Instruments X-series DAQ modules, which come in PCI Express and USB
- Uses the NI-DAQmx API, rather than the legacy NI-DAQ API.
- Not tested on Linux.  The NI drivers may or may not be Linux compatible.
- Obtains accurate time from an inexpensive Trimble ThunderBolt E GPS Disciplined Clock.
- Seismic amplitudes are scaled the same as the older adsend program, to ensure
  compatibility with existing downstream software.
- Runs at a user-configurable sample rate.  Tested at sample rates up to 2000 sps.
- Periodically updates the O/S clock, using time from Trimble GPS.
Will Kohler 7/24/2011


Added in CoincidentStaTriggers option to squash triggers of telemetry spikes. This was
done for the Azores network but could be applicable elsewhere.
Note that I also added a version number to the program which is stored in the log file
AND also echoed to the command line if no args are provided. All EW modules should do this.
Paul Friberg July 19, 2011 (with testing help from Ruben Luis).
On August 18, 2011, I added IgnoreCoincident to ignore the coincident check if more than a
specified number of subnets triggered coincidentally. The idea being that a telemetry glitch
would not cross more than this number of subnets.

hypoinverse 1.3 upgrade
Note that the docs have changed and one command (ZTR has 2 args
instead of one). This new version is really 1.35 and allows hypoellipse
features which have now been integrated in.
Fred Klein did all the code, Paul Friberg integrated with EW and checked it in.
July 18, 2011

Added a new option no_S_on_Z which is a simple flag to
not allow S phases to be associated with picks on vertical
component channels. This option is off by default.
Thanks to Barry Hirshorn for the idea from binder_agl.
Paul Friberg 07/04/2011

Now accepts multiple pids for restart instead of just one!
I made the configfile option a flag (-c) too.
Usage: restart [-c config_file]  [ ...]
Paul Friberg 06/28/2011

Fixed the -e option, which apparently never worked!
Paul Friberg 06/10/2011

Stefan and I fixed the windows compilation which produced bogus numbers and never got
a magnitude (despite running fine). The issue was a output array was filled with
garbage numbers (not zeroed). While this was easy to solve (zero the array
before calling convertWave()), it was not easy to find!
Also, later we added the new configuration option ChannelNumberMap
to map numbered channels to letter code orientations.
New version is 2.1.4 (DOES NOT EFFECT ANY UNIX build of this)
Paul Friberg & Stefan Lisowski 06/08/2011
Later on added in capability to  for Z channel mags, via optional allowVerticals
New version after allowVerticals is 2.1.5
Paul Friberg 06/30/2011

added in a -n option to allow  NO FLUSHING of messages if you want to see all
the messages in a ring at a given instant you can use this new feature.
Paul Friberg 06/01/2011

Fixed a bug where no heartbeats were issued if the Directory Scanning mode was
used to playback data.
Paul Friberg 04/29/2011

modified main tport_getmsg loop such that messages received with return codes
GET_OK, GET_MISS, and GET_NOTRACK are all processed.  Previously, only msgs
returned with GET_OK were processed. Msgs with GET_MISS and GET_NOTRACK returns
were essentially ignored; only the return code was logged.
Lynn Dietz 04/01/2011

updated nmxptool to version 2.0.0
Matteo Quintiliani 01/24/2011

added in tracebuf2.1 detection capability display (to show a conversion factor instead
of data quality flags). This is fully backward compatible with all prior
Kevin Frechette 01/12/2011

Fixed a case where if multiple wave_serverV's were listed, only the first one
was ever polled for data (the rest were marked as duplicates).
Paul Friberg 01/12/2011

any linux module using PTHREAD_STACK set to 8192 can possibly segfault on
64-bit linux (unreliably). The thread stack size was increased to 81920
for Linux #ifdefined statement and all problems went away. This was not
tested on Solaris or Windows or Mac OS X.
Paul Friberg 12/02/2010

tankplayer tools, wave_probe, dumpwave, cleandir, glass, startstopservice
On Windows, added kom.obj to link so that the new kom dependency to logit
is taken into account.
Stefan Lisowski 11/11/2010

tankplayer tools, ew2mseed, dumpwave, getmenu
On Solaris and Unix makefiles, added kom.o to link so that the new kom
dependency to logit is taken into account.
Matteo Quintiliani 11/4/2010

Added parameter EnableLongFileName in the configuration file of menlo_report.
It enables writing arc/sum files with format DATETIME_ID_VER.SUFFIX
(i.e. 201011040932_0000097658_2.arc)
Matteo Quintiliani 11/4/2010

Increased buffer size to 512 bytes for reading a line from the station file.
Same behaviour of pick_ew.
Matteo Quintiliani 8/25/2010

Fixed a misleading print statement when WaveMsg2MakeLocal() failed on a SCNL, it
showed possible spaces in the SCNL that were not really there.
Paul Friberg 8/19/2010

Added QueueSize optional parameter to increase the default from 100
Added SleepMilliSeconds optional parameter to decrease the default from 500ms
Paul Friberg 8/18/2010

*Bugfix You can now comment out the line that includes an email addres
        so nobody gets emailed by statmgr, and you don't need to put a
        fake email address in to get statmgr to start. This is the
        behavior that is desccribed in the config file. Fix by Paul Friberg

- Removed hundredths of second from values of latency.
- Changed the SCNL line output format in order to increase the readability.
  Now each field falls nearly at same column.
- Quality fields are now displayed in hexadecimal.
  Before non-ASCII characters were improperly printed to the terminal.
- Distinguished output for gaps and overlaps.
Matteo Quintiliani 6/22/2010

Removed -D_SPARC from CFLAGS line of makefile.sol. This flag prevented
proper byte-swapping on Solaris for little-endian (Intel) platform.
Ilya Dricker 5/05/2010

*Bugfix to prevent overflow in printing of location code
*Fixed a condition of a bogus 'FULLY in THE GAP' return from waverserver.
 Now if waverserver insists that the request is fully in the gap, but the
 requested startTime is more than 12 hours AFTER the current time, we redefine
 the waveServer FLAG is 'REQUEST-AFTER-THE-TANK'
Ilya Dricker 5/19/2010

Postproc external script is now launched with tow arguments :
date (YYYYMMDD) and time (HHMM) of the processed event.
Change by Frederic Randriamora.
Jean-Marie Saurel 27/12/2010

Added ability to recognize ACTIVATE_MODULE messages to initiate processing; also
added ability to override the set of spectral periods to be processed.
Scott Hunter 05/18/2011

Fixed writing of empty error messages
Scott Hunter 5/17/2011

Restored ability of unix versions to control modules by id; made Windows version
of this more robust
Scott Hunter 6/22/2011

Now allows for up to 10 mailservers; when mail is sent, each is tried in order
until one works.
Scott Hunter 6/29/2011

Uses new transport call to clear ring flag requesting termination of a process
Scott Hunter 6/29/2011

Changed to reflect changes to transport library
Scott Hunter 7/8/2011

I have made very significant changes to the first version. Here is a short list of the main:
1.       Windowed or full-screen - This allows larger traces
2.       Multiple and prioritized waveform sources - One may have multiple waveform sources. The app will automatically select one according to the required station and time interval
3.       List of available stations and time intervals for each source - This allows checking if a waveform source carries the data that we need. Similar to get menu but extended to other waveform sources.
4.       Reads data from wave/Winston servers, tank files (SCNL only), and mini-seed files - I included the latter to be able to check data from continuous archives.
5.       On-screen indication of available data for each station within requested time interval - There is a small check after each station to let the user know that there is data available for the requested time interval.
6.       Facilitated automatic setting of the request time interval based on availability of the sources - I included a button to automatically set the start and end times according to the time interval available from the sources. In case of waveservers it sets the end time to NOW-1 minute (I think) and NOW-21 minutes.
7.       Indication of incorrect date/time settings - Characters turn red if you make an obvious mistake or swap start and end times
8.       Zoom-in and pan buttons as well as drag-to-zoom - Swarm like waveform browsing is really cool to find details.
9.       Missing parameters from pickew are included: NoCoda, RestartLength and MaxGap - I had some requests for this, particularly the nocoda
10.   Tooltips with the pick and coda texts 
11.   Tooltips with the causes for failed picks - Same as before.
2011-07-06 Ruben S. Luis (commited to svn by Stefan)


Environment Variable expansion in .d files
Added file environment/earthworm_commonvars.d for declaring "Earthworm Common Variables"
It is now possible to declare variables like ${...} within .d configuration files
Matteo Quintiliani 11/4/2010




Added a tport_flush call to the transport library; acts as if tport_getmsg were
called repeatedly until no more messages were found, but doesn't incur the
overhead of returning the messages (which would get ignored anyway).
Scott Hunter 5/18/2011

Changed default mail program used by SendMail for MacOSX
Scott Hunter 5/20/2011

Added a tport_detachFromFlag call to support change in flag: instead of
a single value, it now records all individual process IDs put to it
(until TERMINATE is put to it, which effectively replaces the list) --
this prevents the flag from being changed before the target process
reads it (which is now possible, due to making the stop & restart
commands multi-threaded).  tport_getflag now yields TERMINATE if that
has been put; if it hasn't but the process's own ID is in the list, that
is returned; otherwise, 0 is returned.  tport_detachFromFlag is now used
to remove a value from the list (what used to be done by putting a 0).
Scott Hunter 6/29/2011

In order to support legacy modules not using the new transport library,
SHM_HEAD was restored to its original form, and the new list-of-IDs flag
is kept in a distinct ring which is only used for this purpose.  Processes
that do not use the new library will be communicated with via the old flag
field (which has the original overwriting issue, but now contention is only
between legacy modules).
Scott Hunter 7/8/2011

Modified transport library so if a module using the new library is run with
a startstop built against the transport library using the original flag
representation, module will use the old style flag.  Also modified to allow
key for flag ring to be specified in earthworm.d (named FLAG_RING).
Scott Hunter 7/19/2011

Modified getutils to provide a version of GetKey (GetKeyWithDefault) which
takes a default value to return if the specified key does not exist; modified 
transport to use this new function to avoid error messages when FLAG_RING is
not defined (and a default value is used).
Scott Hunter 7/25/2011
