'''This script allows to get information about a given RCF function module
exposed by a distant SAP system.
usage: %prog [options] host sysnr client user functionName
"host" is the server name or IP address where SAP runs.
"sysnr" is the SAP system/gateway number (example: 0)
"client" is the SAP client number (example: 040)
"user" is a valid SAP login
"sapElement" is the name of a SAP function (the default) or a given
group of functions (if option -g is given). If -g is
specified, sapElement can be "_all_" and all functions of
all groups are shown.
Examples
--------
1) Retrieve info about the function named "ZFX":
python asksap.py 127.0.0.1 0 040 USERGDY ZFX -p passwd
2) Retrieve info about group of functions "Z_API":
python asksap.py 127.0.0.1 0 040 USERGDY Z_API -p passwd -g
3) Retrieve info about all functions in all groups:
python asksap.py 127.0.0.1 0 040 USERGDY _all_ -p passwd -g
