  | ### 3.8.4 Info string Syntax: info = string_constant; Purpose: Constitutes the help text of a library. Will be displayed in a SINGULAR session upon entering `help libname.lib;` . Will be part of the SINGULAR documentation if the library is distributed with SINGULAR. See Libraries in the SINGULAR Documentation. Format:
      info="
      LIBRARY: <library_name> <one line description of the purpose>
      AUTHOR:  <name, and email address of author>
      OVERVIEW: <concise, additional information on what is implemented>
      REFERENCES: <references for further information>
      KEYWORDS: <semicolon-separated phrases of index keys>
      SEE ALSO: <comma-separated words of cross references>
      PROCEDURES:
        <proc_name_1>();     <one line description of the purpose>
           .
           .
        <proc_name_N>();     <one line description of the purpose>
      ";
  NOTE: In the documentation, the one line description of the purpose following LIBRARY: will be printed in its own line, starting with the prefix PURPOSE: . REFERENCES, KEYWORDS, and SEE ALSO are optional. Only non-static procedures should be listed in the PROCEDURES: section. A procedure parameter should be included between the brackets `()` only if the corresponding one line description of the purpose refers to it. See Procedures in a library. In the documentation, separate nodes (subsections in printed documents) are created precisely for those procedures of the library appearing n the PROCEDURES: section (that is, for some if not all non-static procedures of the library).

      LIBRARY: absfact.lib   Absolute factorization for characteristic 0

      OVERVIEW:
      A library for computing the absolute factorization of multivariate
      polynomials f with coefficients in a field K of characteristic zero.
      Using Trager's idea, the implemented algorithm computes an absolutely
      irreducible factor by factorizing over some finite extension field L
      (which is chosen such that V(f) has a smooth point with coordinates in L).
      Then a minimal extension field is determined making use of the
      Rothstein-Trager partial fraction decomposition algorithm.
