 =head1 NAME
 
-cgrep - grep the output of a command, only printing stdout/stderr if match
+curiouscat - grep the output of a command, only printing stdout/stderr if match
 
 =head1 SYNOPSIS
 
-cgrep [-v] PATTERN COMMAND...
+cgrep [-v] [-f PATTERNFILE | PATTERN ] COMMAND...
 
 =head1 DESCRIPTION
 
-cgrep runs a command, buffering the output from both standard out and
-standard error, looking for a matching pattern.  If a matching pattern
-is found, stdout and stderr are printed and cgrep exits with the exit
-code of COMMAND.
+curiouscat runs a command, buffering the output from both standard out
+and standard error, looking for a matching pattern.  If a matching
+pattern is found, stdout and stderr are printed and curiouscat exits
+with the exit code of COMMAND.
 
-If the -v switch is passed, cgrep switches into reverse mode where it
-will print if there are any lines not matching PATTERN.
+If the -v switch is passed, curiouscat switches into reverse mode
+where it will print if there are any lines not matching PATTERN.
