These are functions used by ded and related programs.
I began this library late in 1987, incorporating some
functions which I had written for ded. It was not intended to be installed as a
development library (partly because as a developer, I could only
have things installed in
/usr/local by requesting an
administrator to do this), and also because the functions were
intended to be used when building the programs that I
was developing. In the process of developing, I made frequent
changes to the library, which would have required frequent
requests for installing it.
The topic of installing the library came up later (probably suggested by Eric Marshall). I pointed out that the name (my initials) was inappropriate, and that the library as installed should be renamed. Choosing a name is hard, and the easy ones (such as libgen, for general-purpose) were already taken. There were no interesting suggestions. Lacking a suitable choice, it remained “libtd” (aka “td_lib”).
The library can be used in either development- or installed-form:
ded, etc., the library's
configurescript makes a symbolic link to its (versioned, e.g., “td_lib-20170704”) source-directory as just “td_lib” (no version). The application
configurescripts check for this name first.
configurescripts do not find the local build-tree, they will look for the “td” library (which so far has been rarely used as a library name).
The programs which used these functions are documented. There are no manual pages for the common library.
