makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.
Guile-Lib is intended as an accumulation place for pure-scheme Guile
modules, allowing for people to cooperate integrating their generic
Guile modules into a coherent library. Think "a down-scaled,
limited-scope CPAN for Guile".
Also, it can be seen as a code staging area for Guile; the Guile
developers could decide to integrate some of the code into
guile-core. An example for a possible candidate is SRFI-35.
* SSAX, S-Exp-based XML parsing/query/conversion
* HTMLPrag, a permissive ("pragmatic") HTML parser
* Texinfo processing, enabling literate programming
* Unit testing framework ala JUnit
* Logging system
* String routines (wrapping, completion, soundex algorithm)
* OS process chains (think "shell pipes in scheme")
* An LALR parser
* ANSI escape sequence text coloring
* Structured text (plain, texinfo, html)
* SRFI-35 (conditions)
