# Arguments 
# 
#   {DIR} {EX} {CUR} {TINT} {TITLE} {PINIDATE} {PFINDATE}
# 
# where 
# 
#   {DIR} is the dierctory containing the files.
#   {EX} is the exchaneg code, e.g. "BSTP".
#   {CUR} is the currency code, e.g. "USD", "CNY".
#   {TINT} is sampling time interval, e.g. "01h", "01d", etc.
#   {TITLE} is a title for the plot.
#   {PINIDATE} {PFINDATE} are the X-axis range end in the format "{yyyy}-{mm}-{dd}".
# 
# The plot (a PNG image) is written to {stdout}.
