#=== Synopsis ===
#linesvar_toJavaScript src ?sampling ?name ?encoding???;
#
# - $src: file path of a script generated by "regLines.tcl" to simplify
# - $sampling: an optional sampling size that is 10 or more
#   100 is default value
# - $name: an optional function name
#   default name is "linesVar"
# - $encoding: an optional encoding name to output
#   default value is utf-8
#
#output filename has format of "${name}_${sampling}.js"
