/*
*+
* Name:
* CONFIGECHO
* Purpose:
* Displays one or more configuration parameters.
* Language:
* C (designed to be called from Fortran)
* Type of Module:
* ADAM A-task
* Invocation:
* CALL CONFIGECHO( STATUS )
* Arguments:
* STATUS = INTEGER (Given and Returned)
* The global status.
* Description:
* This application displays the name and value of one or all
* configuration parameters, specified using Parameters CONFIG or
* NDF. If a single parameter is displayed, its value is also
* written to an output parameter. If the parameter value is not
* specified by the CONFIG, NDF or DEFAULTS parameter, then the
* value supplied for DEFVAL is displayed.
*
* If an input NDF is supplied then configuration parameters
* are read from its history (see Parameters NDF and APPLICATION).
*
* If values are supplied for both CONFIG and NDF, then the
* differences between the two sets of configuration parameters
* are displayed (see Parameter NDF).
* Usage:
* configecho name config [defaults] [select] [defval]
* ADAM Parameters:
* APPLICATION = LITERAL (Read)
* When reading configuration parameters from the history
* of an NDF, this parameter specifies the name of the application
* to find in the history. There must be a history component
* corresponding to the value of this parameter, and it must
* include a CONFIG group. [current value]
* CONFIG = GROUP (Read)
* Specifies values for the configuration parameters. If the string
* "def" (case-insensitive) or a null (!) value is supplied, the
* configuration parameters are obtained using Parameter NDF. If
* a null value is also supplied for NDF, a set of default
* configuration parameter values will be used, as specified by
* Parameter DEFAULTS.
*
* The supplied value should be either a comma-separated list of
* strings or the name of a text file preceded by an up-arrow
* character "^", containing one or more comma-separated lists of
* strings. Each string is either a "keyword=value" setting, or the
* name of a text file preceded by an up-arrow character "^". Such
* text files should contain further comma-separated lists which
* will be read and interpreted in the same manner (any blank lines
* or lines beginning with "#" are ignored). Within a text file,
* newlines can be used as delimiters, as well as commas. Settings
* are applied in the order in which they occur within the list,
* with later settings overriding any earlier settings given for
* the same keyword.
*
* Each individual setting should be of the form "<keyword>=<value>".
* If a non-null value is supplied for Parameter DEFAULTS, an error
* will be reported if CONFIG includes values for any parameters
* that are not included in DEFAULTS.
* DEFAULTS = LITERAL (Read)
* The path to a file containing the default value for every
* allowed configuration parameter. If null (!) is supplied, no
* defaults will be supplied for parameters that are not specified
* by CONFIG, and no tests will be performed on the validity of
* paramter names supplied by CONFIG. [!]
* DEFVAL = LITERAL (Read)
* The value to return if no value can be obtained for the named
* parameter, or if the value is "<undef>". [<***>]
* NAME = LITERAL (Read)
* The name of the configuration parameter to display. If set to
* null (!), then all parameters defined in the configuration are
* displayed.
* NDF = NDF (Read)
* An NDF file containing history entries which include
* configuration parameters. If not null (!) the history
* of the NDF will be searched for a component corresponding
* to the Parameter APPLICATION. The Parameter CONFIG
* is then optional, but if it too is not null (!) then
* the output will show the differences between the configuration
* stored in the NDF history and the given configuration:
* new parameters and those different from the reference
* configuration (given by Parameter CONFIG) are prefixed
* with "+" and those which are the same as the reference
* configuration are prefixed with "-". [!]
* SELECT = GROUP (Read)
* A group that specifies any alternative prefixes that can be
* included at the start of any parameter name. For instance, if
* this group contains the two entries "450=1" and "850=0", then
* either CONFIG or DEFAULTS can specify two values for any single
* parameter -- one for the parameter prefixed by "450." and another
* for the parameter prefixed by "850.". Thus, for instance, if
* DEFAULTS defines a parameter called "filter", it could include
* "450.filter=300" and "850.filter=600". The CONFIG parameter could
* then either set the filter parameter for a specific prefix (as
* in "450.filter=234"); or it could leave the prefix unspecified,
* in which case the prefix used is the first one with a
* non-zero value in SELECT (450 in the case of this example - 850
* has a value zero in SELECT). Thus the names of the items in
* SELECT define the set of allowed alternative prefixes, and the
* values indicate which one of these alternatives is to be used
* (the first one with non-zero value). [!]
* SORT = _LOGICAL (Read)
* If TRUE then sort the listed parameters in to alphabetical order.
* Otherwise, retain the order they have in the supplied
* configuration. Only used if a null (!) value is supplied for
* Parameter NAME. [FALSE]
* VALUE = LITERAL (Write)
* The value of the configuration parameter, or "<***>" if the
* parameter has no value in CONFIG and DEFAULTS.
* Examples:
* configecho m81 ^myconf
* Report the value of configuration parameter "m81" defined within
* the file "myconf". If the file does not contain a value for
* "m81", then "<***>" is displayed.
* configecho type ^myconf select="m57=0,m31=1,m103=0"
* Report the value of configuration parameter "type" defined within
* the file "myconf". If the file does not contain a value for
* "type", then the value of "m31.type" will be reported instead. If
* neither is present, then "<***>" is displayed.
* configecho flt.filt_edge_largescale \
* config=^/star/share/smurf/dimmconfig.lis \
* defaults=/star/bin/smurf/smurf_makemap.def \
* select="450=1,850=0"
* Report the value of configuration parameter "flt.filt_edge_largescale"
* defined within the file "/star/share/smurf/dimmconfig.lis", using
* defaults from the file "/star/bin/smurf/smurf_makemap.def". If
* dimmconfig.lis does not contain a value for "flt.filt_edge_largescale"
* then it is searched for "450.flt.filt_edge_largescale" instead. An
* error is reported if dimmconfig.lis contains values for any
* items that are not defined in smurf_makemap.def.
* configecho ndf=omc1 config=^/star/share/smurf/dimmconfig.lis \
* defaults=/star/bin/smurf/smurf_makemap.def \
* application=makemap name=! sort select="450=0,850=1"
* Show how the configuration used to generate the 850um map
* of OMC1 differs from the basic dimmconfig.lis file.

* Original version.
* 6-FEB-2013 (DSB):
* Added parameter DEFVAL.
* 11-FEB-2013 (DSB):
* Added parameter SORT and allow all parameters to be listed by
* providing a null value for NAME.
* 11-FEB-2013 (GSB):
* Added ability to read configuration from history entries.
* 13-FEB-2013 (DSB):
* Nullify AST object pointers when the objects are annulled,
* to avoid re-use of dead pointers.
* 14-FEB-2013 (DSB):
* Allow the SELECT feature to be used even if no DEFAULTS file is
* supplied (see the new entry in the "Examples:" section).
* 15-FEB-2013 (DSB):
* Expand the prologue docs, and use NULL in place of zero for pointers.
* 22-FEB-2013 (DSB):
* Guard against seg fault in HistoryKeymap when the NDF does
* not contain the required CONFIG entry in the History
* component.
