\usage{
o_addpath(DIR1, ..., OPTION = "-begin")

o_inpath(...)
}
\arguments{
\item{DIR1}{path specification to add to Octave search path. 
See section \emph{Octave Documentation}.}

\item{...}{other path specifications}

\item{OPTION}{option that specifies how the path should be added. 
Possible values are: \code{'-begin', 0, '-end', 1}.
See section \emph{Octave Documentation}.}
}
\value{
returns invisibly the old value of search path.
}
\description{
Adds a directory at the beginning of Octave search path.

\code{o_inpath} tells if a directory or files are in Octave path.
}
\details{
The .oct files present in directories from the search path are looked up 
when an object or function is requested but not loaded in the current session.
The files are watched and automatically reloaded in case modification.
