## \brief
#  \english
#  mapping link function from source_path to target_path
#  \param source_path source link from
#  \param target_path is target link to
#  \param math_rule is regular
#  \param debug is show debug message
#  \param test_run is run for test
#  make_link no return vale
#  \endenglish

#  \chinese
#  把來源路徑下的子資料夾連接到目標路徑
#  \param source_path 來源路徑，會把該路徑下的所有符合 math_rule 的資料做 link
#  \param target_path 連接的目標路徑
#  \param math_rule 符合條件，可以不傳入任何值
#  \param debug 顯示除錯訊息
#  \param test_run 測試過程
#  make_link 不回傳任何值
#  \endchinese

#  \note use '*' must add '\s' before it, like '\s*'
