Instalation:
------------

First place somewhere ls-config binary, or make it from source

Then if You woud like use it with national translation, then You muas build
it form source and then copy *.mo files according to You system

Usage:
------

Remember to call ls-config always with -f parameter,
wich give ls-config inormation wich config file use.

Then this program operate in three based modes:
-g (get) for reading values (default)
-s (set) for store values
-h (help) for display help message
both parameter (-g and -s) nedd to give it variable path
(internal configuration variable path)

for exapmle read info value from config file:
ls-config -f config -g info

Then You can set this value to another
ls-config -f config -s info -d "Somethint to write"

But when You wand to addn new configutation variable you must
specify his type:
ls-config -f config -s someint -d 10 -p int

You can remove (unset) variable too. This is subfunstion of setting:
ls-config -f config -s someint -u

When reading You cent use following flag:
-v - read only variable valut
-t - read only variable type
-c - read only variable element count (sense only in types: array, list, group)
-i - read only variable index (sense only in type: array, list) 
-n - read only variable name

and sometimes usable 
-q  - to wori in quiet mode usable in scripts.

For example to read variable somevar type, where variable in group foo:
ls-config -f config -g "foo.somevar" -t

For detailed list of parametera (long options available too) run ls-config
in help mode:
ls-config -h

Configuraiton files:
--------------------

Detailed configuration file shema are publicated on:
http://www.hyperrealm.com/libconfig/
And his gramar on:
http://www.hyperrealm.com/libconfig/libconfig_manual.html#Configuration-Files

there are only short describe:
configuration = setting-list | empty
setting-list = setting | setting-list setting
setting = name (":" | "=") value (";" | "," | empty)
value = scalar-value | array | list | group
value-list = value | value-list "," value
scalar-value = boolean | integer | integer64 | hex | hex64 | float | string
scalar-value-list = scalar-value | scalar-value-list "," scalar-value
array = "[" (scalar-value-list | empty) "]"
list = "(" (value-list | empty) ")"
group = "{" (setting-list | empty) "}"
empty =

smaple configuration file and script are available on sample/ directory
config - samble configuration file
script - sample script, then read info variable from config file
