+     "This package provides a pre-commit git hook to check basic LaTeX
+syntax for the use of package developers.  It is installed by copying
+it into the @file{.git/.hooks} file.  It then checks the following
+file types: @file{.sty}, @file{.dtx}, @file{.bbx}, @file{.cbx}, and
+@file{.lbx}.  It performs the following checks:
+
+@itemize
+
+@item each line must be terminated by @samp{%}, without a space before it;
+
+@item empty lines are allowed, but not lines with nothing but spaces in them;
+
+@item @code{\\begin@{macro@}} and @code{\\end@{macro@}} must be paired;
+
+@item @code{\\begin@{macrocode@}} and @code{\\end@{macrocode@}} must be
+paired;
+
+@item @code{\\begin@{macro@}} must have a second argument;
+
+@item one space must be printed between @samp{%} and @code{\\begin@{macro@}}
+or @code{\\end@{macro@}}. @samp{%} must be the first character in the line;
+
+@item four spaces must be printed between @samp{%} and
+@code{\\begin@{macrocode@}} or @code{\\end@{macrocode@}};
+
+@item @code{\\cs} argument must not start with a backslash.
