+efax is a small ANSI C/POSIX program that sends and receives faxes
+using any fax modem (Class 1, 2 or 2.0).*
+
+efax is smaller and easier to install than HylaFAX or mgetty+sendfax.
+As one user put it "EFAX is a nice simple program for single user systems."
+
+The "fax" command, a shell script, lets you send, receive, view and print faxes.
+In larger systems, faxes can be sent by printing to a "fax" printer and received
+faxes can be e-mailed as MIME attachments to an administrator for distribution.
+efax can also pass incoming data calls to a getty program.
+
+The efax package includes "efix," a program to convert between various image file formats.
+To fax Postscript files you will need Ghostscript.
+To view faxes you can use any program tha displays PGM files.
+efix can also convert received files to Postscript or HP Laserjet formats for printing.
+
+This program has only a command-line interface.
+If you need a GUI-based fax solution, install efax-gtk instead.
+
+*Any hardware-based fax modem, that is.  If you have a "software modem," a so-called "Linmodem,"
+then you'll instead need to download the alpha version of efax and modify this SlackBuild script
+accordingly.
+
+The alpha release can be found here:

+# 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 ':' except on otherwise blank lines.
