# use \n or %newline% for a new line (it will be replaced by the used EOL char(s) - LF, CR/LF, CR).
# use \t or %ws% for an indentation step, it will be replaced according to the current document's indent mode.
# use \s to force whitespace at beginning or end of a value ('key= value' won't work, use 'key=\svalue').
# use %key% for all keys defined in the [Special] section.
# use %cursor% to define where the cursor should be placed after completion. You can define multiple
#     %cursor% wildcards and use the "Move cursor in snippet" to jump to the next defined cursor
#     position in the completed snippet.
# You can define a section for each supported filetype to overwrite default settings, the section

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Each existing unread and subsequent new emails after the script is started are 
passed as Mail objects to "process_email" function.Function header is provided
but processing implementation is left to the user. Error logs are currently sent
to a rotating log file (in the same directory as the script) and to STDOUT. 
Instead of polling or checking the server for new emails every now and then,
IMAP IDLE check is utilized.  Ensure that the IMAP server supports IDLE command
and allows at least 5 minutes of idling*** and uses the default ports for this 
script to work. Tested to work with Gmail and default installations of MS 
Exchange Server.
