.SH NAME
euscan \- manual page for euscan (git) - A tool to detect new upstream releases.
.SH DESCRIPTION
.SS "Usage:"
.IP
euscan [options] <package>
euscan [\-\-help, \fB\-\-version]\fR
.SS "Available options:"
.HP
\fB\-C\fR, \fB\-\-nocolor\fR \- turn off colors on output
.HP
\fB\-q\fR, \fB\-\-quiet\fR \- be as quiet as possible
.HP
\fB\-h\fR, \fB\-\-help\fR \- display the help screen
.HP
\fB\-V\fR, \fB\-\-version\fR \- display version info
.HP
\fB\-1\fR, \fB\-\-oneshot\fR \- stop as soon as a new version is found
.TP
\fB\-b\fR, \fB\-\-brute\-force=\fR<level> \- define the brute force <level> (default: 2)
bigger levels will generate more versions numbers
0 means disabled
.TP
package
\- the package (or ebuild) you want to scan
