CHICKEN-BUG(1)						      General Commands Manual						    CHICKEN-BUG(1)

NAME

       chicken-bug - generates a bug report from user input

SYNOPSIS

       chicken-bug [ filename | OPTION ...  ]

OPTIONS

       -help  Show usage information.

       -to-stdout
	      Write bug report to standard output instead of writing it to a file.

       -      Read user input from standard input, even if files are given on the command line.

DESCRIPTION

       chicken-bug generates a bug report file that collects user-input, optional files and system information obtained from the installed CHICKEN
       executables and libraries. Non-option arguments given on the command line are inserted into the bug report. If no option is given, or if  -
       has been passed on the command line, then a description of the problem is read from standard input, until EOF (CTRL-D) or a line consisting
       only of "." (period) is read.

       The bug report will be written to a file in the current directory, which should be sent to CHICKEN maintainers as it contains various  use-
       ful bits of information that make it easier to classify the problem described.

       Bug  reports  should be as detailed as possible. It is also very helpful to include code that reproduces the problem. The more detailed the
       input and the more thorough the description is, the easier you make it for the CHICKEN developers to help you.

BUGS

       Submit bug reports by e-mail to chicken-janitors@nongnu.org
