.SH SYNOPSIS
.sp
\fBautodep\fP [options] <command>
.SH DESCRIPTION
.sp
Auto dependency (autodep) builder is a tool for the analysis of accessed files during
the build of a package. It also can be used for runtime dependencies analysis.
.sp
The tool can trace, log and block access to files of given packages.

Notes
.IP [1] 5
FUSE filesystems are slower than a normal one. A Program accesses many files
while launching, so this will take more time than usual.
.IP [2] 5
Loading of Dynamic libraries and direct syscalls will not be logged.
.SH EXAMPLES
.SS Get the potential dependencies for net\-irc/xchat:

autodep emerge \-\-blockpkgs x11\-misc/util\-macros emerge net\-irc/xchat
.SS Get the potential dependencies for net\-irc/xchat package, and show accessed files:
.sp
autodep \-\-files emerge net\-irc/xchat
.SS Get the runtime dependencies of a xchat and show accessed files:
.sp
autodep \-\-fusefs \-\-files xchat
