+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.

+${PRGNAM}: ${PRGNAM} ( installer for Haskell )
+${PRGNAM}:
+${PRGNAM}: ghcup makes it easy to install specific versions of ghc on GNU/Linux,
+${PRGNAM}: macOS (aka Darwin) and FreeBSD and can also bootstrap a fresh Haskell
+${PRGNAM}: developer environment from scratch. It follows the unix UNIX
+${PRGNAM}: philosophy of do one thing and do it well.
+${PRGNAM}:
+${PRGNAM}: Similar in scope to rustup, pyenv and jenv.
