Unless you mean you have a list of very specific bad practices for it to check for, it is difficult for an algorithm to deduce the intent of a program well enough to see whether it's a good or poor solution to the problem, except at very small scopes.

To a certain degree that's what an optimizing compiler does; taking a close look at what's been optimized where might be illuminating if your compiler can be convinced to be sufficiently spammy.

Tracing your program's system and library calls would also be a place to start. What does the program spend most of its time doing? Does it really need to be waiting when it is? Is it doing I/O efficiently? Is it polling when it could be using a blocking call instead? Is it doing inexplicable repetitive things? Is it calling malloc way more often than a sane program would need to? etc. etc.

NAME

       info - readable online documentation

DESCRIPTION

       The  Info  file	format is an easily-parsable representation for online documents.  It can be read by emacs(1) and info(1) among other pro-
       grams.

       Info files are usually created from texinfo(5) sources by makeinfo(1), but can be created from scratch if so desired.

       For a full description of the Texinfo language and associated tools, please see the Texinfo  manual  (written  in  Texinfo  itself).   Most
       likely, running this command from your shell:
	      info texinfo
       or this key sequence from inside Emacs:
	      M-x info RET m texinfo RET
       will get you there.

AVAILABILITY

       ftp://ftp.gnu.org/pub/gnu/texinfo-<version>.tar.gz
       or any GNU mirror site.

REPORTING BUGS

       Please send bug reports to bug-texinfo@gnu.org, general questions and discussion to help-texinfo@gnu.org.
