The Alog Toolbox contains a set of command line post-mission utility
applications. Each command line tool either (a) modifies a given alog
file to produce a new smaller alog file, or (b) analyzes a given alog
file, producing a concise report.

Examples of tools that produce a modified alog file:

\begin{packed_itemize}
\item \app{alogclip}: Remove data from the front or end of the file based on time.
\item \app{alogclip}: Make new alog file clipping front/back lines based on time.
\item \app{aloggrep}: Make new alog file keeping lines matching given pattern(s).
\item \app{alogrm}: Make new alog file removing lines matching given pattern(s).
\item \app{alogsplit}: Make folder of new alog files, one for each unique variable.
\item \app{alogpare}: Make new alog file retaining dense info around marked events.
\item \app{alogcat}: Make new alog file from one or more alogs not overlapping in time.
\end{packed_itemize}

Examples of tools that analyze and produce a report from an alog file:

\begin{packed_itemize}
\item \app{alogscan}: Report stats for each unique variable/app in the alog file.
\item \app{aloghelm}: Report one of a few helm event reports given an alog file.
\item \app{alogiter}: Report information about cpu load given an alog file.
\item \app{alogcd}: Report collision detection information given an alog file.
\item \app{alogavg}: Report averages given a file of X-Y values.
\item \app{alogbin}: Report data binned into specified ranges
\item \app{alogmhash}: Report key information related to the mission hash.
\item \app{alognpos}: Report vehicle nav position suitable for a trajectory plot.
\end{packed_itemize}
