Small tail workalike that performs output coloring
mtail is a small tail workalike that performs output coloring using ansi escape sequences although the sequences are overridable, so you could cause it to output something else, e.g. html font tags, if you really wanted to. mtail is written in python, is fairly small, and should be relatively platform-independent.
It has a config file that can contain an arbitrary number of entries, each of which has a series of regular expressions to indicate which files to color according to which entry. for each entry, the config file specifies a coloring scheme using regular expressions and, optionally, filters to apply to each line before coloring for example, to strip out extra info, etc.. the config file also may override the predefined colors and the escape sequences or whatever actually used to perform the coloring.
