MCHF atomic-structure package: support libraries and utilities

Abstract
The libraries and utilities that form part of the MCHF atomic-structure package are described. Among the utilities is a LEVELS program that produces an energy level table and a LINES program that process the transition data from a series of LSJ calculations as a line list.

Title of program: MCHF_LIBRARIES
Catalogue Id: ABZU_v1_0

Nature of problem
As mentioned in the previous paper [1] that describes the organization of the MCHF atomic structure package, the MCHF programs are classified as being either angular or radial in nature. Each type uses routines from libraries designated MCHF_LIB_ANG, MCHF_LIB_COM (common to both) or MCHF_LIB_RAD, respectively. The routines in these libraries and some useful utilities are described.

摘要
本文对构成MCHF原子结构程序包的各类库文件与实用工具进行了阐述。其中实用工具包含可生成能级表的LEVELS程序，以及可将一系列LSJ计算得到的跃迁数据处理为谱线列表的LINES程序。

程序名称：MCHF_LIBRARIES
目录编号：ABZU_v1_0

问题性质
正如前文文献[1]中所述（该文献阐述了MCHF原子结构程序包的架构），MCHF程序按性质可分为角向程序与径向程序两类。两类程序分别调用指定库中的子程序：MCHF_LIB_ANG、MCHF_LIB_COM（两类程序通用）或MCHF_LIB_RAD。本文对上述库中的子程序及部分实用工具进行了详细说明。
